Frank N. Foster (1845-1909) was born in Little Chelsea, Middlesex, England, and died in Seattle, Washington. He immigrated to the United States in the early 1850s. From 1863 to 1865 he served in the Union Navy in the American Civil War as a landsman on the USS Ohio, based out of Boston, Massachusetts. Thereafter, he settled in Little Falls, Minnesota, where he married Mary E. Foster (b. Sumner) in 1867 and was employed as a bookkeeper for George Spencer & Co., a grain business. By 1900 the Fosters had moved to Brooklyn, New York, where Foster worked as a photographer, and finally, sometime prior to 1909, they settled in Seattle, Washington. In 1886, Foster wrote a letter to Mary Baker Eddy to order a copy of Science and Health with Key to the Scriptures. Based on the records available, we have found no further information concerning his involvement with Christian Science.
