Notes:
Dr. Frederick A. Brentlinger (ca.1802-1876)¹ graduated from the Pennsylvania College of Washington in 1825⁷.
He came to Wheeling VA later that year (1825), and for a few years he kept a small drug store on Union Street (now called 11th Street). In 1845, he opened the first "Drug and Prescription" store in Wheeling, on 12th Street above the McLure house. ¹

At some point he teamed with W. J. Armstrong and formed the Brentlinger & Armstrong drug store. The earliest newspaper reference I could find to this name was in 1852².

Brentlinger & Armstrong split up in 1855¹, and Brentlinger was on his own for a while. At some point he teamed up with William T. Derry and formed Brentlinger & Derry. The earliest reference I could find to this was in 1864⁵.

Derry left to form his own drug store in 1875⁶, and that left Brentlinger on his own again. Brentlinger passed away in 1876⁸, but it seems his wife continued to run the store until sometime on or after 1886⁵.

The bottle is embossed: vertical on front: BRENGLINGER / & ARMSTRONG vertical on right side panel: WHEELING vertical on left side panel: VA base: (glass pontil scar) It looks like the base has a key-mold mark that got distorted by the glass pontil scar.
