Charles Herman Tozier was born on February 24, 1875 in Waterville, Maine, to Cyrus Greely and Annie Osgood Tozier. He attended high school in Somerville and entered Harvard in 1894. He earned an B.S. in 1898 and continued his studies at Harvard Medical School, where he earned an M.D. in 1901. He spent a year at Harvard Dental School studying diseases of the mouth and left in June 1902 to join a medical practice in Boston.

Tozier married Edith Downs Peck in the fall of 1902; the couple had one son, Charles William, in 1910. Tozier became interested in photography as early as the 1920’s. He traveled throughout North and South America to photograph wildlife and took microscopic photographs of plant and animal life while working in laboratories at Harvard. He also exhibited and lectured on his photography around the Boston area.

Edith died in 1935. The following year Tozier returned to Harvard as a Research Fellow in Dental Science. In 1937 he married Helen Clark Hopewell. He continued as a Dental Science Fellow until 1944 when he became a Research Fellow in Visual Education. He remained in this position until his death from heart disease on January 1, 1947.

The Tozier slides were assigned numbers based on the order in which they were found stored in the Herbaria. This order has been preserved.


The glass slides were likely part of a larger collection of images and camera equipment that was donated to Harvard and divided between departments. They were previously stored with the Herbaria collections.
