Notes:
William N.H. Maack (1820-1904) was born in Hamburg Germany⁸. His obituary claims he was the first man to brew Ale in the Washington DC⁹. He had a long career as a beer brewer, mineral water (aka soda pop) manufacturer, and bottler. He had many business partners through the years, as discussed below.

    Henke & Maack at Olive and Green streets
The earliest venture into the bottling business I can find for Maack is when he teamed up with Louis Henke and took over the mineral water & vinegar factory at Olive and Green streets in Georgetown on August 21st 1850². On Apr 15, 1851, Henke & Maack announced they had renovated their whole mineral water apparatus ¹⁰. 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.

    Maack & Arny at Olive and Green streets
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. On March 1, 1854, Maack & Arny announced their copartnership was mutually disolved, and that the the company would continue as Arny & Shinn¹².

    William N.H. Maack at 4 1/2 and N Streets
Maack didn't stay idle for long. On May 1, 1854, he announced that he had commenced manufacturing mineral water, and had purchased the "Worlds Fair premium Soda Water apparatus" for his factory at 4 1/2 and N Streets⁶. The 1855 city directory lists his address as 426 4 1/2 Street, whereas subsequent city directorys list it at 428 4 1/2 Street. I'm not sure if he had 2 separate buildings during that period, or if the 1855 entry was a mistake. But various newspaper articles refer to the address as the corner of 4½ and N Streets, so I'm confident that is referring to the same location as "428 4½ Street".
On June 30, 1856, John McKeon³ announced that he had sold the machinery, bottles, fixtures, etc belonging to his mineral water factory to William N.H. Maack¹³. Below that announcement was an announcement by Maack that he was now able to supply the public with the best Porter, Ale, Cider and Mineral Water. This is the earliest document indicating that Maack sold beer, although it does not specify that he actually brewed the beer himself.
The 1858 City directory lists William Bosse at the same address as William Maack, so apparently they were teamed up at that time.
Then there was an announcement on June 13th 1859 that Haugstetter & Koehler had purchased a Mineral Water and Bottling establishment from Mr. Maack and Mr. Bosse , but it did not say what the address of the establishment was¹⁴. I wonder if it was at 426 4½ Street, and that Maack moved to 428 4½ Street after that, as Maack contined to be listed at that latter address in city directories until 1865. The article claimed that Haugstetter & Koehler had taken ownership all bottles with the names "Bosse" or "Maack" on them. But there was an announcement made a few days later (June 18th 1859) where Bosse refuted that claim, and made it clear that the Bottles did not convey¹⁵, and that he still owned all bottles with his name on them. My guess from all this is that Maack had teamed up with Bosse at some point, but their partnership didn't work out, so they sold their mutual ownings and went their separate ways.
    Beer Brewer
Starting in 1860, Maack is listed as a brewer in city directories, and the address of his establishment was listed as a brewery (as well as his home). He continued to be listed as a brewer until 1877.

    William N.H. Maack at 1304 4½ St SW
This is the modern day address near the intersection of 4½ and N Streets, so I believe that this is the same building referred to as both "Corner of 4½ and N Streets" and "428 4½ Street".

    William N.H. Maack at 1300 6th St SW
In 1878-1892, Maack shows up in city directories at 1300 6th Street SW. He shows up as a bottler or mineral-water manufacturer during these years, not a brewer.
