The First Scientific Member
The first African-American to be admitted/elected into the MSMA, although in this limited “scientific” status, was Oswald Garrison Smith (1915 – 2002) of Clarksdale. (See this month’s “images in Mississippi Medicine” on page 214.) He was born September 4, 1915 in Vicksburg, the son of Mr. and Mrs. Perry Monroe Smith. He attended the public schools of Mound Bayou and attended Bolivar County Training School there.
