Question: What association did the woman whose museum is located in the Bolling–Gatewood House help found?

<P0-S0> The Bolling–Gatewood House is a historic cottage in Holly Springs, Mississippi, USA. <P0-S1>  It is home to the Ida B. Wells-Barnett Museum, named for former slave, journalist, and suffragist Ida B. Wells. <SEP> <P1-S0> Ida Bell Wells-Barnett (July 16, 1862 – March 25, 1931), more commonly known as Ida B. Wells, was an African-American journalist, newspaper editor, suffragist, sociologist, feminist, Georgist, and an early leader in the Civil Rights Movement. <P1-S1>  She was one of the founders of the National Association for the Advancement of Colored People (NAACP) in 1909. <SEP> <P2-S0> Mary Eileen Ahern (October 1, 1860 – May 22, 1938) was a librarian and leader of the modern library movement.She has been selected as one of the "100 of the Most Important Leaders We Had in the 20th Century" in the "American Libraries" list published in 1999. <P2-S1>  She was an important influencer and early organizer of libraries in America. <P2-S2>  Mary Ahern was a crusader for the value of public libraries in educating the public. <P2-S3>  In the first issue of the journal she edited, "Public Libraries", as reported in the "World Encyclopedia of Library and Information Services" Mary said, “There is only one solution of all social problems, an increase in intelligence, a gradual education of the people.” <P2-S4>  The best source of this education, she believed, was potentially the public library. <P2-S5>  This was a time in history when Andrew Carnegie was building libraries across the nation and Melvil Dewey created the Dewey Decimal System and help found the American Library Association. <P2-S6>  Mary wrote and spoke about this optimistic vision in the same editorial, the public library “is the broadest of teachers, one may almost say the only free teacher. <P2-S7>  It is the most liberal of schools; it is the only real people’s college.” <P2-S8>  The "World Encyclopedia" states, “ She saw a librarian as a teacher on all occasions.” <P2-S9>  Mary shared this vision with government leaders, teachers and librarians everywhere she went, throughout her long career. <SEP> <P3-S0> The East Central Conference was an athletic conference from 1947 to 1969 based in Eastern Indiana, considered as one of the regional superconferences in the state. <P3-S1>  The conference began with 12 schools, though had turnover within its first year, mainly having to do with gym issues. <P3-S2>  Pendleton and Greenfield, larger schools, refused to play in Cambridge City's gym, deeming it too small to play in. <P3-S3>  The conference felt otherwise, and forced the two schools out of the conference. <P3-S4>  Williamsburg, on the other hand, had the opposite problem; its gym was found to be too small for conference play, and moved them out as well. <P3-S5>  To fill their spots, the conference recruited Milroy, Morristown, and Morton Memorial to join the fold. <P3-S6>  While the conference did grow to 13 schools, by 1956 it had started to splinter. <P3-S7>  Three schools left to found the Eastern Indiana Athletic Conference in 1956, while in 1962 four schools left to help found the Tri-Eastern Conference. <P3-S8>  The formation of the TEC in 1962 almost caused the ECC to fold, as it was left with five members. <P3-S9>  However, the Hancock County Conference's six schools were merged into the fold, giving the conference new life. <P3-S10>  However, the conference did not have long, as the formation of the Big Blue River Conference left the conference with three schools by 1968, two of which were scheduled to be closed at the end of the 1968-69 school year. <P3-S11>  The sole remaining member, Morton Memorial, opted to join the BBRC that next year.
