Emil Alexander de Schweinitz (January 18, 1866 – February 15, 1904) was an American bacteriologist.



He was born in Salem, North Carolina, and was the son of Moravian Bishop Emil de Schweinitz. He attended Nazareth Hall High School and the Moravian College of Bethlehem, Pennsylvania, and received a PhD from the University of North Carolina in 1882 and another from Göttingen in 1886.

On returning to the United States he taught chemistry in Tufts College, Massachusetts, and then became a Professor of Chemistry at the Agricultural and Mechanical College of Kentucky. After becoming associated with the chemical division of the Agricultural Department, Washington, D.C. in 1888, he was appointed as director of the biochemical laboratory of the department's Bureau of Animal Industry in 1890, a position he remained in until his death. He was a member of the American Public Health Association from 1896. He was also chair of chemistry and toxicology in the Columbian University and later its dean.

He specialized in bacteria and immunity, and studied the bacterial products of tuberculosis, hog cholera and glanders. Among other essays, he published Laboratory Guide (1898).

He lived at 1023 Vermont Avenue, Washington, and was a member of the Chevy, Cosmos and Metropolitan Clubs. He died suddenly of uremia in 1904.
