The Wilsons' contributed the following information about the Tebbetts: James was a Physician in Manchester N.Y in 1851; around 1854 he devised the formula and his son Andrew J. joined him in an Apothecary business; the younger son George W.O. started working as a clerk about the same time; James died in 1865 and the sons had bottles embossed for the brand in 1867; Andrew retired in the 80s and George kept the business going until about 1887.
I found James Allen Tebbetts first listed in 1852 as an "Apothecary" at 17 Merrimac Block, Manchester, N.H. In 54 he was listed as a "Physician" and in 56 he moved his business to 7 & 8 Crosby's Block. By 1864, his occupation was "Physician and Apothecary" at 112 Elm. The product was listed for sale at least as early as 1865 (see ad below) and at least as late as 1901 (Morrison & Plummer catalog). Tebbett's Hair Regenerator was again for sale after the turn of the century. It was being made then by Tebbetts Brothers of Manchester. I assume these would have been in different bottles that I have not seen.
Tebbetts bottles come in several colors. Most of them are deep purple. The one shown is from my personal collection. George Waddy has a nice light one in his collection (view gallery). Photograph courtesy of George Waddy. This peach one (view) was sold in Heckler's Auction in 2003 (wow!).
The 1870 Detroit Review of Medicine and Pharmacy examined this preparation and found it to contain 7.44 grains of lead per fluid ounce.
Three of these sold in a Glassworks auction in March of 2009. The hammer prices ranged from $275 to $1,900. Add the 15% buyer's fee and the bottles sold for $302 to $2090. That's a pretty wide range, but the $2,000 one was a perfect example in the lightest possible color. The $300 range ones were darker in color and not mint.
