Frederick Heim was born in Neustadt, Bavaria, Germany.  He emigrated to America in 1864 and found work in Newark, New Jersey.  A few years later he traveled west to a new home in Salt Lake City, Utah.  In 1876 arrived in Deadwood, in the Dakota Territory at age 36.

He was one of the first gold rushers to come to Deadwood and doing so was able to purchase about an acre of prime land in what would become downtown.  In it he installed a garden, a picnic and erected a bandshell and called it Union Park in honor of America's Centennial.  At some point within the year he started a brewery on the land as well.  He ran the Union Park and Brewery until May of 1879 when the value of the real estate became too tempting and he offered the land for sale in the Pioneer-Times.  In September of that year a fire destroyed much of Deadwood and the town had to completely rebuilt.

In April of 1880 Frederick Heim and dairyman James Anderson purchased the Gayville Export Beer Brewery from Nick Pesold and they ran the brewery on the outskirts of Deadwood that summer.  The next year Anderson sold his share to Frederick C. Silkenson.  Silkensen in turn purchased Heim's share on August 11th. But Silkensen had overextended himself and on September 19th the Gayville Export Beer Brewery went into foreclosure due to unpaid debts to former partner Anderson.

The sheriff's sale occurred on the 20th of October and the purchaser was a jeweler named J. H. Heckmann.  Heckmann kept Heim on as Brewmaster and together they ran the brewery for several years.  In 1884 Heckmann's name dropped off the advertisements but it is unknown to me whether that means a change in ownership or simply the ascendance of the reputation of Heim's Beer.  

By 1885 the Heim's Beer was apparenly selling itself.  The brewery existed but it wasn't advertising.  In 1888 it appears Frederick Heim moved to the town of Buffalo Gap, where he left the brewery business and took ownership of a mine.  

Frederick Heim died on February 23rd, 1902 at the age of 61.
