Services for Samuel A. Hartman, a taxicab owner and former president of the Diamond Cab Co., will be held at 1 p.m. today at the Loring Byers funeral establishment, 8728 Liberty Road.
Mr. Hartman, who was 87 and lived on Chesterfield Avenue, died Wednesday at the Meridian Nursing Center/Multi-Medical of complications after surgery.
He began driving a cab in the mid-1920s and soon became a charter member of the Association of Independent Taxi Operators, which became the Diamond Cab Co.
Mr. Hartman was president of the company in the 1930s and 1940s and managed the Diamond Cab baseball team that won the Maryland Amateur Baseball League's 1937 championship.
Though he had once owned a fleet of cabs, he went into semiretirement and finally had only one.
Born to a German family in Danzig, now Gdansk, Poland, Mr. Hartman came to Baltimore after World War I. He studied pharmacology in Poland and the United States, but he worked as an usher at the Gayety Theater before entering the taxicab business.
His wife, the former Lena D. Geschwendt, died Sept. 26.
Mr. Hartman is survived by a son, Paul Hartman of Wheaton; two grandchildren; and five great-grandchildren.
