Company Names, addresses, dates:
  Henke & Maack, Corner Olive & Green Sts, Georgetown DC (1850-1853) ^1,2

Notes:
William N.H. Maack (1817-1904)³ and Louis Henke took over the mineral water & vinegar factory at Olive and Green streets in Georgetown on August 21st 1850¹.
On Apr 15, 1851, Henke & Maack announced they had renovated their whole mineral water apparatus ⁴. The announcement also had a request for "3 boys, colored, slaves preferred". It also said they had a large supply of vinegar on hand - my guess is that they stopped manufacturing vinegar at this time, as I've found no mention of vinegar from their company after this.
On January 10th, 1853, Henke & Maack announced they had disolved their partnership, and that Maack would continue the business and pay off all their debts³. I don't know how long Maack was the sole proprietor, but on June 27th of that same year (1853) there is a want ad for a horse from Maack & Arny at Olive and Green streets ¹¹, so apparently Maack had quickly teamed up with Charles Arny.
