As a young man he was so proficient in baseball, basketball, and track that he received offers of athletic scholarships at several schools. He chose to attend St. Stephen's College (now

. The founding director of the lab was Clarence Cook Little, who had previously been the President of the University of Michigan. Thus, aware of Bittner's research, Little offered him a position as a research associate at the Jackson Laboratory. In 1940 Bittner became the lab's Assistant Director, where he remained until December 1942. After a fire at the Jackson Laboratory in 1947, Bittner was one of the main contributors of replacement mice because he still had the purebred mouse strains needed to continue their research. In January 1943 he became the George Chase Christian Professor of Cancer Research and Director of the Division of Cancer Biology at the

Cancer research

By far, the greatest impact of Bittner's contributions to cancer research was the discovery in 1936, while working at the Jackson Lab, that a cancerous agent, which he called a "milk factor", could be transmitted by cancerous mothers to young mice while nursing. Bittner used two families of mice: in Family A, almost all the mice, across many generations, developed breast cancer; in Family B, cancer seldom occurred. He then took a number of newborn mice from Family A, away from their cancerous mothers, and set them to nurse with immune mothers in Family B. Next, Bittner took babies from the immune Family B and set them to nurse with cancerous mothers from Family A. The result was that the young mice switched their cancer tendencies. Three out of four mice, which came from healthy Family B, developed cancer and died of it, while those originally from Family A remained healthy. Bittner noted that something in mouse milk appeared to pass the disease along. In other words, nursing mice transmit this agent, or "Bittner virus", in their milk, which ultimately leads to tumors in their offspring. In addition, Bittner felt that genetic and hormonal influences, along with the milk agent, contributed to the origin of cancer. In 1966, it was proven that Bittner's "milk factor" was a virus that remained dormant during the early life of the young mouse but produced cancer when hormonal conditions were right in middle age. The Bittner virus is now known as the
Mouse mammary tumor virus Mouse mammary tumor virus (MMTV) is a milk-transmitted retrovirus like the HTL viruses, HI viruses, and BLV. It belongs to the genus ''Betaretrovirus''. MMTV was formerly known as Bittner virus, and previously the "milk factor", referring to t ...

and was a member of their board of directors from 1945 to 1951. He also served on the editorial advisory board of ''Cancer Research'' from 1941 to 1957. Throughout his career, Bittner served on numerous committees dealing with cancer research. During the summer of 1947, he was a member of the Medical Teaching Mission to Austria, sponsored by the Unitarian Service Committee, of the World Health Organization to "promote international exchange of medical and scientific knowledge." Bittner authored, or co-authored, over 240 papers on cancer research, and contributed chapters to several books. He lectured widely in this country and abroad and attended many national and international meetings.


Honors

Bittner received many awards, citations, and medals during his career. The most notable include the following: * 1941 The Alvarenga Award - American College of Physicians in Philadelphia * 1950 Medal of the American Cancer Study * 1950 Honorary Doctor of Science Degree - Bard College, Annandale-on-Hudson, New York * 1951 1st Comfort Crookshank Award - Middlesex Hospital Medical School, London * 1957 Bertner Foundation Award - M.D. Anderson Hospital and Tumor Institute, University of Texas Medical School, Houston * 1957 Doctor of Medicine and Surgery ''honoris causae'' - University of Perugia, Italy
