John Daniel Kraus was born June 28, 1910. He received his Bachelor of Science degree in 1930 and his doctorate in physics in 1933, both from University of Michigan. During his time at Michigan he did millimeter and meter wavelength radio experiments and also nuclear research with the University's newly completed cyclotron.
During World War II, Kraus worked at the Naval Ordnance Laboratory degaussing electromagnetic fields of steel ships to make them safe from magnetic mines, and then at Harvard's Radio Research Laboratory developing receivers and antennas for radar counter-measures. He joined the faculty at Ohio State University in 1946 and remained there for his entire academic career. He was the Taine G. McDougal Professor of Electrical Engineering and Astronomy, and founded and directed the Ohio State-Ohio Wesleyan Radio Observatory. When a grant of $2,000 allowed him to buy steel, he and his students built one of the first radio telescopes in the United States, an array of 96 helices, completed in 1953, that operated at 250 MHz. Kraus then went on to design and build the "Big Ear" radio telescope, completed in 1965. "Big Ear" was a fixed parabolic antenna, measuring 110 by 21 meters; it received reflected rays from a tiltable flat reflector panel, and the parabolic antenna in turn focused the signal to a central point at ground level. With it, Kraus and other astronomers studied some of the most distant known objects at the edge of the universe, and produced extensive surveys of the radio sky. His many other antenna designs include the bi-directional W8JK wire beam antenna widely used by radio amateurs, the corner reflector, and the helical beam antenna, used in communication and global positioning satellites.
Following the completion of the all Sky Ohio State radio source survey and the loss of funding from the NSF, Big Ear was used for many years by Kraus and his students to search for intelligent life elsewhere in the Universe. Kraus founded Cosmic Search, a magazine devoted to the search for extra-terrestrial intelligence, also including historical articles about radio astronomy, which he edited and published from 1979-1982.
A dedicated teacher, Kraus had a profound and lasting effect on his students; he maintained friendships with many of his students after they completed their degrees, and followed their careers with interest. Books Kraus authored included Antennas, Radio Astronomy, and Electromagnetics, all of which had multiple editions and were translated into many languages, as well as the autobiographical Big Ear and Big Ear Two. Kraus retired from Ohio State in 1980, but continued to work at the observatory as Professor Emeritus into the 1990s.
Kraus was a long-time radio amateur, licensed as W8JK. Through the 1930s, Kraus maintained regular contact with two missionaries in Belgian Congo, one a doctor running a medical clinic. Their transmissions served as a means for many missionaries of the Presbyterian Church in the United States and their extended families in the U.S. to transmit both routine and emergency news in a timely way, and allowed the doctor to arrange medical consultations with specialists in Ann Arbor. Kraus contributed many articles to CQ, the radio amateurs' journal; in 1996, Dayton Hamvention honored Kraus as the recipient of its Special Achievement Award, and in 2001, CQ named Kraus to the inaugural class of its Amateur Radio Hall of Fame.
Kraus served on both the National Science Foundation and Associated Universities committees involved in the earliest planning for the development of the National Radio Astronomy Observatory, and in 1955, he was part of the small group that recommended Green Bank WV as the site for NRAO.
In 1976 Kraus and his wife, Alice, donated the Kraus Wilderness Preserve, 80 acres of woodland and meadow adjacent to their home, to Ohio Wesleyan University for use by Ohio Wesleyan and Ohio State Universities, and they endowed scholarships to enhance environmental learning for students at the two universities.
Kraus was elected as a Fellow of the Institute of Electrical Engineers (IEEE) in 1954 and to the National Academy of Engineering in 1972. His many awards and recognitions included the U.S. Navy Meritorious Civilian Service Award in 1946, the Ohio State University Sullivant Medal in 1970, and the Outstanding Achievement Award of the University of Michigan in 1981. He received the 1984 Centennial Medal, the 1985 Edison Medal and the 1990 Heinrich Hertz Medal from the IEEE, as well as the Distinguished Achievement Award of the IEEE Antennas and Propagation Society in 2003.
Kraus married Alice Linnea Maria Nelson in 1941; they had two sons, John Jr. and Nelson.
Kraus died in Columbus, Ohio, on July 18, 2004.

Scope and Contents of Collection
John Kraus' papers are separated into series, and then into units as needed.
General Correspondence Series: Kraus filed his general correspondence alphabetically in three separate chronological sequences, one for the 1930s through mid-1940s, one for the mid-1940s through the mid-1970s, and one for the mid-1970s until his death in 2004. These separate sequences have been combined into one alphabetical sequence. Kraus' filing scheme has been generally retained: alphabetical by correspondent and chronologically within each correspondent, with some correspondents being company or institution names, but most being personal names. Reprints, photographs, and other materials have been retained with the relevant correspondence as originally filed by Kraus. The correspondence covers a very wide range of both personal and professional interests and topics. Kraus' manilla filing folders, which were discarded, were sometimes annotated with various addresses or phone numbers of the correspondent, and occasionally with names of spouses and names and ages of children. Correspondence related to Kraus' publications, patents, lectures, and awards, as well as the correspondence he included in his subject files, has been retained with the appropriate material as Kraus originally filed it. The general correspondence covers the period 1926-2004. Size: 6.5 linear feet. Click here for an itemized listing of the General Correspondence.
Four sets of correspondence have been organized as separate units.
- Antenna Correspondence Unit: This unit includes correspondence from 1935-1940 originally filed by Kraus in a single folder labeled "Antenna Correspondence." The majority of the correspondence is on the flat top beam antenna, but other types of antennas, their construction and operation, and other issues related to antennas are also discussed. Kraus labeled one small subset of the correspondence as "Used in Big Ear" and another as "Not yet used." Remaining correspondence in the unit has been divided by year, but not sorted or indexed otherwise. See also the Amateur Radio Miscellaneous correspondence in the General Correspondence Series. Correspondence related to the efforts to save the Big Ear telescope and its subsequent demolition is filed with the Big Ear telescope materials in the Antennas Unit of the Notes and Papers Series. Size: 0.5 linear feet.
- ON4CSL Correspondence Unit: In November 1933 Kraus, operating as W8JK, made ham radio contact with ON4CSL in the Belgian Congo, a station operated by Carroll Stegall, an American missionary who had lived in the Congo for 20 years. Kraus began regular contact with Stegall, and their on-air conversations became conduits for news that bypassed the multiple months needed for paper mail. In 1936, Kraus helped Dr. George Westcott set up his own station at his clinic in the Congo, ON4CGW. Kraus maintained regular contact with both Stegall and Westcott, and soon their transmissions served as a means for many missionaries of the Presbyterian Church in the United States and their extended families in the U.S. to transmit both routine and emergency news in a timely way, and allowed Westcott to arrange medical consultations with doctors in Ann Arbor. Kraus, Stegall, and Westcott continued in contact until the fall of 1939, when the Belgian government ordered all amateur stations shut down because of the war in Europe. This unit includes correspondence between Kraus and missionary families in the U.S. and with the Executive Committee of Foreign Missions about the messages going to and from the Congo, as well as Kraus' notes about his transmissions. See also correspondence with Ray F. Cleveland, Carroll Stegall, and George Westcott in the general correspondence series. This unit includes correspondence and transcriptions of transmissions for the period November 1933 through November 1939. Size: 1 folder. Note: This material has been filed under the letter O in the General Correspondence alphabetical sequence.
- John E. Pfeiffer Radio Astronomy Correspondence Unit: This collection of letters and articles was gathered by John Pfeiffer while he was preparing his book on radio astronomy and its history, The Changing Universe (Random, 1956). Pfeiffer gave the letters to Kraus, who transmitted them to the Ohio State University Library, Division of Special Collections, in 1976. Kraus kept copies of all the material, and it is the copies that are here included, along with some additional material collected in 1959 by Reed Crone, Kraus' research assistant, and the correspondence related to the transmission of the papers to the Library. The letters include correspondence with members of the Karl G. Jansky family, with Grote Reber, George Southworth, and Walter Baade. Also included are articles on Jansky and his discoveries from Bell Laboratory Record, a transcript of a radio broadcast on May 15, 1933, and C.M. Jansky's 1956 presentation about his brother to the American Astronomical Society. Copying of correspondence is prohibited; for permissions contact the Ohio State University Library, Division of Special Collections. The correspondence covers the period 1933-1976. Size: 1 folder. Note: This material has been filed under the letter P in the General Correspondence alphabetical sequence.
- Family Correspondence Unit: This unit includes correspondence to/from Kraus' parents, Edward and Lena Kraus, Kraus' sister Margaret Kraus Ramsdell, Edward T. Ramsdell, Alice Nelson Kraus, and John D. Kraus. John Kraus' letters to family from Germany in 1934 are accompanied by a journal for the trip. A typed transcript of letters written from Europe in 1926 by Edward H. Kraus, prepared by John Kraus, Jr. in 1989, is also included; the originals of these letters are with the Edward H. Kraus archive at University of Michigan. Correspondence in this unit is from 1926-1957. See also the Kraus Family Materials Unit in the Notes and Papers Series. Size: 0.5 linear feet.

See also antenna-related materials in the Patents Series, in the Newspaper Clippings Unit in the Collected Publications Series, and with general correspondence, amateur radio correspondence, and antenna correspondence. Size: 1.0 linear feet. Click here for an itemized listing of folders in the Antennas Unit.
- Big Ear Subunit: In 1956 Ohio State University and Ohio Wesleyan University signed a joint agreement for the cooperative establishment and operation of a radio observatory on a site owned by Ohio Wesleyan. Ohio State University would be responsible for construction of the radio observatory and associated facilities on the site. Construction was begun in 1956 and completed in 1965. "Big Ear" was a fixed parabolic rectangle, measuring 110 by 21 meters; it received reflected rays from a tiltable flat reflector panel, and the parabolic antenna in turn focused the signal to a central point at ground level. With it, Kraus and other astronomers studied some of the most distant known objects at the edge of the universe, and produced extensive surveys of the radio sky. In December 1982, Ohio Wesleyan decided to end the joint agreement signed in 1956 in order to sell the land to a developer. Despite opposition from Kraus and the radio astronomy community over an extended period, the telescope was demolished in 1998 to add nine holes to an adjoining golf course. This subunit includes materials from 1950-2004 related to the Big Ear telescope: a copy of the 1956 joint agreement; correspondence, press releases and clippings related to the battle to save the telescope; material on contracts with NASA and the US Air Force for use of the antenna; and material on the antenna demolition. For Kraus' description of his immediate personal reaction to the news in 1982 that Ohio Wesleyan was selling the telescope site to developers, see chapter 27 of his book Big Ear Two and also the 5th draft for the book and chapter.

- Elements of Electromagnetics Subunit: This text by John D. Kraus, published in 1949 by Long's College Book Company and printed by Edwards Brothers, Inc., was written especially for the undergraduate introductory course in field theory course at Ohio State University. This subunit includes 1948-1949 editorial correspondence about the production process, and Kraus' personal copy of the book with annotations and corrections. Size: 0.25 linear feet.
- Our Cosmic Universe Subunit: This subunit includes materials from 1976 to 1999 on Our Cosmic Universe, published by Cygnus-Quasar Books in 1980. Originally the book was to have been called Eyes and Ears on the Universe, and was to have been published by Scientific American in their Illustrated Library series. Kraus's manuscript was reviewed and edited, a contract was signed with Scientific American, he received prepublication royalty checks, and a sample book, with blank pages but the proposed illustrated cover and cloth spine (now included in this subunit), were sent to Kraus. For unknown reasons, Scientific American then dropped the project, and Kraus went on to modify the manuscript and publish it in 1980 under his Cygnus-Quasar imprint as Our Cosmic Universe. Based on some of the early correspondence and photo permission requests, Kraus may also have considered calling the book ABCs of Space or ABCs of SETI, envisioning it as an expansion of the ABCs column in his magazine Cosmic Search. This subunit includes 1976-1978 editorial correspondence with Scientific American, a November 1977 version of the Eyes and Ears of the Universe manuscript, correspondence and notes from 1976 to 1999 related to the writing of the Eyes and Ears on the Universe manuscript and the writing and publication of Our Cosmic Universe, and soft-cover and cloth-bound copies of the book.

- Cosmic Search Unit: This unit includes materials dated 1974-1984 related to the magazine Cosmic Search, founded, published, and edited by John Kraus. The unit includes a full set of the magazine: vol. 1, no. 1, January 1979, through vol. 4, no. 1, serial number 13, 1982. The purpose of Cosmic Search was to present all aspects of the search for intelligent life in space, often refered to as the search for extraterrestrial intelligence, or SETI, in a popular but responsible manner. Kraus hoped with the magazine to generate funds to help finance scientific research at a time of dwindling state and federal support, and a non-profit organization, Cosmic Quest, Inc., was formed to act as publishing entity. However, the magazine ran at a loss, and ceased publication after three years, following a brief but unsuccessful attempt to find another editor. The magazine AstroSearch, published by Delta Vee, Inc., a nonprofit space corporation encouraging citizen involvement in space activities, was intended to be a merger of Cosmic Search and Delta Vee's CQ-ET Newsletter, but published only 5 issues, all in 1983; issues are included in this unit. Cosmic Search article authors included Jocelyn Bell Burnell, Ronald N. Bracewell, Arthur C. Clarke, Norman Cousins, Frank D. Drake, C.M. Jansky, Jr., Nikolai Kardashev, John Kraus, Philip Morrison, Carl Sagan, Walter Sullivan, and Virginia Trimble. A regular feature of the magazine was a column written by Kraus called, "ABCs of Space," which gave short explanations of basic concepts ranging from the Doppler effect to star spectra. Kraus also wrote a set of articles on "The First 50 Years of Radio Astronomy," intended for publication in Cosmic Search as a 5-part series. Only parts 1-2 were actually published, but the draft of part 3 and notes for part 4 are included here. The unit includes correspondence and other materials related to content, editorial, and administrative matters, as well as manuscripts, original figures, and original photographs. Folders labeled by Kraus with specific issue numbers often contain miscellaneous correspondence and other materials which are perhaps related to but not included in the issue, along with correspondence received during the period in which an issue was being prepared. Correspondence about the 1982-1983 attempt to find another editor, and about the merger of Cosmic Search and AstroSearch is also included. Size: 1.5 linear feet.
