Mr. Hamilton's diaries cover a sixty-six year period, 1879-1943. The diaries reveal many interesting incidents from his personal life, the School for the Blind, local, national and world events. The diaries for the years 1885 to 1889 give a vivid picture of Hamilton's experiences as an undergraduate at the University of Rochester.

The Collection contains minutes of Board of Directors' and stockholders' meetings and a stock ledger of the Charles C. West Coal Company, Inc. of Rochester, New York, a private stock company whose shares were owned exclusively by family members, the general manager, and the firm's attorney. The company had a long and varied existence previous to its incorporation, however. It was first begun by Charlotte A. Heacock in 1883 and was called the C. A. Heacock Coal Company. In 1890 Charles C. West became a partner in the firm and it became known as Heacock and West. The following year Charlotte Heacock retired and Edward L. Heacock became head of the firm.

Charles Howell Ward (1862-1943), osteologist and preparateur of anatomical models, was the son of Professor Henry A. Ward, founder of Ward's Natural Science Establishment in Rochester. He attended Alfred College for two years after he returned from sea; after a stint with the Army in the Southwest, he joined his father's business, in the Department of Human Anatomy, in 1885. He left his father's firm in 1899 to found the Charles H. Ward Anatomical Laboratory, which he continued to operate until his death.
