William Bauman Jr. (1866 - July 16, 1933) was an American draftsman. Born in Maryland, Bauman Jr. worked for the General Land Office from the 1890s through at least the mid-1920s. He married Cora Walker (March 15, 1868 - January 18, 1904) on September 12, 1899, with whom he had two children. After retiring from the General Land Office (the historical record does not tell us when he retired), he moved to Florida with his second wife, Rosa, and died in Tampa on July 16, 1933.
