Twelve women have led MENC: The National Association for Music Education, including current president Lynn Brinckmeyer--six of them in the first fifty years of MENC's history. Frances Elliott Clark, known as the "Mother of the Conference," oversaw the founding of the Music Supervisors' National Conference (MSNC) in 1907 at a gathering in Keokuk, Iowa. Two women served the organization as president during its first quarter century: Henrietta G. Baker (1912-13) and Elizabeth Casterton (1913-14). This article highlights the other three female presidents of the Music Educators National Conference (as renamed in 1934) who served in the first fifty years of the organization: Mabelle Glenn (1928-30), Lilla Belle Pitts (1942-44), and Marguerite V. Hood (1950-52). Mabelle Glenn used her presidency to challenge music educators to consider the relationships between music, instructional methods, and the goals of music education. During her presidency, Lilla Belle Pitts continued the themes evident in Mabelle Glenn's writings and responded to the calls for educational reform by espousing the integration of music with other academic subjects. Marguerite V. Hood's first contributions to MENC grew from her role as Montana's state supervisor of music and her passionate advocacy for music in rural schools. As MENC president, Hood expanded this view to promote equality of musical opportunity for all students in the United States and across the globe. (Contains 49 notes.)
