Two years later, in 1866, he and fellow aspiring brewer Leonhard Eppig partnered to form the Germania Brewery on 22-32 George Street. In 1876 Fischer left the firm and partnered with Charles Frese and purchased the Robert Selg brewery on 238-252 Scholes Street.

In 1886 Fischer had recovered enough to purchase the Hartford Gambrinus Brewery from George Sicher. Fischer promptly renamed it the Hubert Fischer Brewery. He ran the brewery until national Prohibition forced it closed in 1920. Hubert Fischer died on the 19 January 1929. He was 93 years of age.

By 1864 he had struck out on his own, partnering with Hubert Fischer to start a new brewery at 22/32 George Street. . Leonhard assumed sole proprietorship in 1876. That same year he was naturalized as a US citizen.

Leonhard C. Eppig died on April 9th 1893. His brewery continued on as the Leonard Eppig Brewing Co., Germania Brewery until Prohibition shut it down in 1920. During the dry years, it was bottling soda water and ginger ale as the Interboro Cereal Beverage Company. In 1935 the factory was purchased by the descendants of George Ehret, who ran it as a brewery for 14 years under the Geo. Ehret Brewing Co. name. In 1949 the firm was purchased by the Schlitz Brewing Co. of Milwaukee. They brewed Schlitz Beer there until the plant closed in 1973.
