In 1927 she became a charter member of the Altrusa Club of New York City, an organization for Professional and Business Women started in 1917 for the purpose of providing community service. Gilbreth's government work began as a result of her longtime friendship with Herbert Hoover and his wife Lou Henry Hoover, both of whom she had known in California (Gilbreth had presided over the Women's Branch of the Engineers' Hoover for President campaign). Lou Hoover urged Gilbreth to join the Girl Scouts as a consultant in 1929. She remained active in the organization for more than twenty years, becoming a member of its board of directors. During the Great Depression, President Hoover appointed Gilbreth to the Organization on Unemployment Relief as head of the "Share the Work" program. In 1930, under the Hoover administration, she headed the women's section of the President's Emergency Committee for Employment and helped to gain the cooperation of women's groups for reducing unemployment. During World War II Gilbreth continued advising governmental groups and also provided expertise on education and labor issues (especially women in the workforce) for organizations such as the War Manpower Commission, the Office of War Information, and the U.S. Navy. In her later years, Gilbreth served on the Chemical Warfare Board and on Harry Truman's Civil Defense Advisory Council. During the Korean War she served on the Defense Advisory Committee on Women in the Services. Author and educator Gilbreth had a lifelong interest in teaching and education. As an undergraduate at the University of California, Berkeley, she took enough education courses to earn a teacher's certificate, and her doctoral dissertation at Brown University was on applying the principles of scientific management to secondary school teaching. While residing in Providence, Rhode Island, Gilbreth and her husband taught free, two-week-long summer schools in scientific management from 1913 to 1916. The Gilbreths also discussed teaching the Gilbreth System of time-and-motion study to members of industry, but it was not until after her husband's death in 1924 that she created a formal motion-study course. Gilbreth presented this idea at the First Prague International Management Congress in Prague in July 1924. Her
