Sarah G. Crosby (1832-1915) was a resident of Albion and then Waterville, Maine. She befriended Mary Baker Eddy in the early 1860s when both were patients of Phineas P. Quimby in Portland, Maine. They corresponded regularly throughout the 1860s and, in 1864, Eddy lived with the Crosbys for a few months in Albion, Maine. Sarah G. Crosby was left impoverished after her husband, Albert Crosby (1824-1883), deserted her and moved out West to Montana. To support her children, she trained as a stenographer and worked in the Maine court system until 1888. In 1877, Eddy offered Crosby paid work as a stenographer, to take notes for Eddy in one of her classes. After 1877, the relationship soured, though when Crosby wrote to Eddy in 1903 asking for money, Eddy obliged, sending her former friend fifty dollars (equal to approximately $1,300 in 2014). Crosby would later talk to several early biographers of Mary Baker Eddy and would accuse Eddy of being a spiritualist and of stealing Christian Science teachings from Quimby.
