Bethune planned on going to architecture school at Cornell. Instead, in 1876, she took a job working as a draftsman at
Richard A. Waite and
F.W. Caulkins, well-known architects in Buffalo, New York. In 1881, after five years in Waite's office, she opened an independent office with her husband, Robert Bethune, in Buffalo, earning herself the title of the nation's first professional woman architect, which she announced at the Ninth Congress of the Association for the Advancement of Women. In 1891, William Fuchs became their third firm partner, and the three of them did everything from small residential to larger institutional buildings. Bethune was elected a member of the
Western Association of Architects (WAA) in 1885. She later served a term as a vice president of the W.A.A. She was named the first female associate of the
American Institute of Architects (A.I.A.) in 1888 and in 1889, she became its first female fellow. In 1891, she refused to compete in a design competition for the Women's Building at the
World's Columbian Exposition in
Chicago because men were paid $10,000 to design buildings for the fair while the women got only $1,000. The Bethune firm also designed the Denton, Cottier & Daniels music store, one of the first buildings in the United States to utilize a
steel frame and poured concrete slabs. Three other Bethune buildings are still standing today: the Iroquois Door Plant Company warehouse; the large Chandler Street Complex for the Buffalo Weaving Company; and the
Witkop and Holmes Headquarters (1901), which was listed on the
National Register of Historic Places in 2014. She was involved of the design of one hundred fifty buildings in the Buffalo and New England areas during her career. == Work ==
