Alvin F. Robinson, an obstetrician and gynecologist who delivered thousands of babies in Washington during his more than five-decade career, died Aug. 24 at the District home of his granddaughter, Marianne Robinson Pingree. He was 100.

The cause was respiratory failure, said his daughter, Jacqueline Robinson Browne.

Dr. Robinson began his practice in 1943 at the old Freedmen’s Hospital, which became Howard University Hospital. In the mid-1950s, he became the first ­African-American staff physician at the District’s Providence Hospital, according to his daughter, and later coordinated its residency program.

Alvin Franklin Robinson was born in Washington. After the deaths of his parents, he moved to McLean, where he was raised by an uncle. He attended District schools and graduated in 1932 from Dunbar High School, where he was class president.

He received a bachelor’s degree from Howard University and, in 1939, a medical degree there. Dr. Robinson taught at Howard University’s College of Medicine for four decades.

His professional memberships included the American Board of Obstetrics and Gynecology, the Medical Society of the District of Columbia and the National Medical Association, where he served as secretary, his daughter said. He frequently contributed to the Journal of the National Medical Association.

Dr. Robinson was a charter member of Beta Nu Boule, the Northern Virginia chapter of Sigma Pi Phi fraternity.

His wife of 55 years, the former Jacqueline Johnson, died in 1996. Their son, Alvin T. Robinson, who also was an obstetrician, died in 1982 in the crash of a Pan American World Airways jetliner in Kenner, La. Survivors include his daughter, Jacqueline Robinson Browne of Brookline, Mass.; two grandchildren; and a great-granddaughter.
