Dr. Thomas F. Rumbold, whose previous wife had died, leaving him two small children, Mildred and Frank, married Charlotte E. Lederberger. She and her husband lived in St. Louis, where they raised his children and their four daughters: Charlotte, Estella, May, and Caroline. A foster child, Oliver Will Phillips, was also raised by the family. Dr. Rumbold was an internationally known medical specialist of the ear, nose and throat; he also invented a splint for gun-shot fractures of the leg and thigh, and spray procedures treating the nasal passages and throat. Charlotte Rumbold was a social reformer who worked in St. Louis for the Open Air Playground Committee in 1902, spent nine years as playgrounds supervisor for the city starting in 1906, and compiled a descriptive report on terrible housing conditions for the city's Civic League in 1908. She also organized a large, successful Pageant and Masque in Forest Park in 1913 to celebrate the city’s 150th anniversary. A suffragist and popular speaker, her motto was, "If we play together, we will work together." In 1914, the St. Louis Globe-Democrat named her the "best-known young woman in St. Louis." The following year, when she asked for a raise from St. Louis as New York was recruiting her for a $4,000-per-year position, despite public outrage, the city's Board of Aldermen voted against her raise given that "she is not a voter." She resigned and moved to Cleveland, Ohio, to work for the Chamber of Commerce as secretary of the city planning committee, where she studied Cleveland's housing situation and made recommendations. She was responsible for Cleveland's first group housing in 1917, and she continued her work to eliminate slums and improve housing conditions and public spaces. She died at age 90 in Cleveland. Caroline Rumbold (1877-1957), eight years younger than Charlotte, received her bachelor's degree at Smith College in 1901, a master's degree at Washington University (St. Louis) in 1903, and a Ph.D. in plant pathology at Washington University in 1911. She worked for the United States Department of Agriculture in various positions from 1903 as a scientific aid through 1942, when she retired from her position as associate pathologist. She also taught botany at the University of Missouri. In 1928 she embarked on a world tour, which she documented in many letters to her siblings and in three diaries.
