Notes:
William N.H. Maack was born in 1822 in Germany. American Brweries II² says the WNH Maack & Co brewery lasted only from 1874 to 1875, however DC directories list William NH Maack as a brewer in the 1860s, and as a bottler in the 1880s.
Maack was teamed up with someone named "Arny", as evidenced by the "MAACK & ARNY" bottle below. Presumably this was the same Charles W. Arny who teamed up with Riley Shinn to form "Arny & Shinn" at 57 Greene Street in Georgetown from about 1854 to 1862³. So presumably "MAACK & ARNY" were teamed up prior to 1854.
The National Intelligencer Newspaper mentions Henke & Maack in a list of companies that took out a license for a wagon under the laws of "Wash Corp" sometime during the months of July, August & September of 1850⁴. From this information, plus the fact that the "Henke & Maack" bottle below is torpedo shaped (typical of very early soda bottles), I beleive that Henke & Maack were teamed up before Maack & Arny.
