Amanda Clement was born in Hudson, South Dakota, then part of the Dakota Territory, on March 20, 1888, to Harriet Clement, one of the original settlers of Eden, South Dakota, and her husband Phillip, who died when Amanda was very young. In 1904, Clement traveled to Hawarden, Iowa, to watch her brother Hank pitch in a semi-professional game. The umpire for the amateur game taking place before Hank's did not show, and Hank suggested that Amanda, who had played baseball with her brothers and was knowledgeable about the game, serve as the umpire. In so doing, Clement became the first woman paid to umpire a baseball game. Her performance was so well received that she was hired to umpire further semi-professional games. Clement's umpiring career lasted six years, during which she officiated games in North Dakota, South Dakota, Minnesota, Iowa, and Nebraska. Unlike in modern games, during Clement's time games only had one umpire, who stood behind the pitcher and was responsible for calling strikes and balls, whether balls were fair or foul, and whether runners reached bases safely. Despite the danger umpires faced during this era Clement was treated respectfully by both players and fans, and became respected for her serious style and because she was insusceptible to bribery. Her popularity was so high that baseball marketers emphasized her officiating of games to bring in crowds. In 1906 Clement wrote an editorial for the Cincinnati Enquirer arguing that women made better umpires than men because men would not speak abusively towards female umpires. She would repeat this idea in interviews with other newspapers. Clement, a Congregationalist, refused to umpire on Sundays and stayed in the homes of clergymen while umpiring on the road. Clement earned between $15 to $25 per game, which she used to fund her college education, attending Yankton College for two years followed by two years at University of Nebraska. While at Yankton, she refereed high school basketball games, possibly the first woman to do so, captained the college's women's basketball team, ran track, was a gymnast, and was by her own approximation the state's best tennis player. A number of additional accomplishments in sports have been attributed to Clement, but cannot be confirmed because of poor record keeping at the time. These claims include winning tennis championships in Iowa and South Dakota and setting world records in shot put, sprinting, hurdling, and baseball, where it is claimed that Clement threw a baseball 275 feet.
After umpiring
Although Clement spent only six years serving as an umpire on a regular basis, she continued to serve intermittently until her forties. Following her time as a regularly serving umpire, Amanda Clement spent several years teaching physical education at the University of Wyoming, the Jamestown, North Dakota, high school, and other schools in North Dakota and South Dakota. Clement also managed several Y.W.C.A.s, including one in La Crosse, Wisconsin. Clement also served as the coach of Hudson Independent basketball team, organized tennis tournaments, and served as a newspaper reporter, police matron, typesetter, justice of the peace, and as the city assessor for the town of Hudson. In 1929, Clement moved back to South Dakota to care for her mother, who was ill. Following her mother's death in 1932, Clement moved to Sioux Falls, South Dakota, where she spent twenty-five years as a social worker before retiring in 1966. Clement died in Sioux Falls on July 20, 1971.
