David Mitchell was a Perfumer in Rochester, New York from 1859 until 1865. In 1859, his business was called Establishment Mitchell, and it was at 49 State Street. The business was also located at 110 State Street, but that could have been due to renumbering. From 66 to 67, his wife Cecelia was listed at the same address. Frank B. Mitchell (probably their son) took over the business in 1868. He was listed as a "Mf'g Perfumer" from 1868 to 73. During the later years, they turned over the manufacturing and marketing to William L. Markel & Bro. The business the Mitchell's ran was called "Mitchell & Co.," and "Establishment Mitchell."
The other half of the advertisement was for Mitchell & Co., at the same address. There was a part of the ad that discussed Mitchell's Cocoa-Cream - possibly the same product. The picture shown is the only known Mitchell's Hair Tonic bottle. It's similar to a Lyon's Kathairon bottle, except the Mitchell's is clear.
