William Bohne (1827-1906), author of handbook for opticians, first textbook by an American optometrist

William Bohne (1827-1906) was a teacher in Germany before emigrating to the United States in 1852. He worked as an optician (as optometrists were known at that time) in New Orleans in the second half of the nineteenth century. His book, Handbook for Opticians, which went through three editions, appears to have been the first optical care textbook written by an American optometrist. This paper gives a brief biographical sketch of Bohne and a description of the contents of the third edition of his book.
