This collection contains personal and official correspondence to and from poultry leaders covering the period 1928 to 1973. There is also information on the life and work of Dr. Warren, from his birth in 1890 to his death in 1994. An autobiography written in 1975 and a brief history of his forefathers, traced to North Carolina in 1786, is a part of the collection. Copies of newspaper articles concerning Warren's contributions to the poultry industry, certificates and awards given him during his career, his induction into the Poultry Hall of Fame in 1971, and many photographs of him at work and with colleagues and friends are included. Four bound volumes, covering the years 1917 through 1966, contain reprints of 88 scientific papers, mostly on genetics, published by Dr. Warren during that 49 year period. Research notes, sketches and the final draft of work completed on Drosophila melanogaste in 1918, are of interest. Copies of many speeches the donor made around the world, together with pencilled annotations, show his wide field of interest in genetics. Also included is an audiotape recording of induction speeches for the honorees when Warren and four other industry leaders were inducted into the Poultry Hall of Fame in a 1971 ceremony at the National Agricultural Library. A seven inch reel of 6 mm. motion picture film entitled "Forming an Egg", one of Warren's areas of expertise, rounds out this collection.
