Ernest Thompson Seton sought Eastman's counsel in forming the Woodcraft Indians, which became a popular group for boys. The New York YMCA asked both Seton and Eastman to help them design YMCA Indian Scouts for urban boys, using rooftop gardens and city parks for their activities. In 1910, Seton invited Eastman to work with him and Daniel Carter Beard, of the Sons of Daniel Boone, to found the Boy Scouts of America (BSA). Luther Gulick also consulted with Eastman to assist him and his wife Charlotte to develop the Camp Fire Girls. With his fame as an author and lecturer, Eastman promoted the fledgling Boy Scouts and Camp Fire Girls. He advised them on how to organize their summer camps, and directly managed one of the first Boy Scout camps along the shores of the Chesapeake Bay. His daughter, Irene, worked as a counselor at a Camp Fire Girl camp in Pittsburgh. In 1915, the Eastman family organized their own summer camp, Camp Oáhe, at Granite Lake, New Hampshire, where the whole family worked for years. Eastman served as a BSA national councilman for many years. National spokesman Eastman was active in national politics, particularly in matters dealing with Indian rights. He served as a lobbyist for the Santee Sioux between 1894 and 1897. In 1911, Eastman was chosen to represent the American Indian at the Universal Races Congress in London. Throughout his speeches and teachings, he emphasized the importance of seeking peace and living in harmony with nature. In 1903, President Theodore Roosevelt assigned Eastman to helping Sioux (Dakota, Nakota, Lakota) tribal members to choose English legal names, in order to prevent individuals and families from losing allotted lands due to confusion over cultural naming conventions and spellings. Eastman was one of the co-founders of the Society of American Indians (SAI), which pushed for freedom and self-determination for the American Indian. From 1923 to 1925, Eastman served as an appointed US Indian inspector under President Calvin Coolidge. The Calvin Coolidge administration (1923-1929) invited Eastman to the Committee of 100, a reform panel examining federal institutions and activities dealing with Indian nations. The committee recommended that the government conduct an in-depth investigation into reservation life (health, education, economics, justice, civil rights, etc.). This was commissioned through the Department of Interior and conducted by the Brookings Institution, resulting in the groundbreaking 1928 Meriam Report. The findings and recommendations served as the
