First elected in 1992 to represent Maryland's 6th District, Roscoe G. Bartlett is now serving his ninth term in the United States House of Representatives. Prior to his election to Congress, he pursued successful careers as a professor, research scientist and inventor, small business owner, and farmer.

One of three scientists in Congress, Bartlett served in the 110th Congress as Ranking Member of the Seapower and Expeditionary Forces Subcommittee, as a member of the Subcommittee on Oversight and Investigations of the Armed Services Committee, as a senior member of the Science Committee, serving on two of its subcommittees, Energy and the Environment, and Research and Science Education, and as a senior member of the Small Business Committee, serving on two of its subcommittees, Contracting and Technology and Urban & Rural Entrepreneurship.

Bartlett attended Columbia Union College where he majored in theology and biology and minored in chemistry, and earned a Master’s degree in human physiology at the University of Maryland at College Park. Bartlett taught anatomy, physiology and zoology at the University while simultaneously earning a Ph.D. in human physiology.

Bartlett engaged in research in addition to teaching, as an Assistant Professor at Loma Linda University School of Medicine in California. He relocated to Howard University in Washington, D.C. as a Professor of physiology and endocrinology at its Medical School. Bartlett left to pursue research full-time first at the National Institutes of Health (NIH) and then at the U.S. Navy's School of Aviation Medicine (U.S.NAMI) in Pensacola, Florida. While at U.S. NAMI, Bartlett invented a series of break-through respiratory support equipment. He holds the basic patents for rebreathing equipment which recycle the oxygen from exhaled air in closed systems.

In 1961, Bartlett returned to Maryland and farming after he purchased his 145-acre then-dairy farm on the Monocacy River in Frederick County. While running his farm, he worked at the Johns Hopkins Applied Physics Laboratory (APL) as director of a new 30-member research group in Space Life Sciences. The group designed and conducted a series of pioneering research experiments that contributed to NASA's successful Gemini, Mercury and Apollo missions to land men on the moon and bring them back safely to earth. Dr. Bartlett later joined IBM and worked there on numerous biomedical engineering and defense-related projects. With IBM's assistance, he formed his own research and development company, Roscoe Bartlett and Associates. He also taught anatomy and physiology to nursing students at Frederick Community College.

In 1999, the American Institute of Aeronautics and Astronautics (AIAA) awarded Dr. Bartlett its Jeffries Aerospace Medicine and Life Sciences Research Award. Recognizing the importance of scientific aeronautics and space discoveries to the field of medicine, the award was established in 1940, and is presented annually to recognize outstanding career research accomplishments in aerospace medicine and space life sciences.

Roscoe and his wife Ellen have been married for more than 40 years. They have ten children, fifteen grandchildren and two great grandchildren.  Dr. Bartlett annually donates scholarships for undergraduate students in his district majoring in mathematics, science or engineering at the colleges located in Maryland’s Sixth district.
