Berg was born in Stettin (now Szczecin, Poland) in Pomerania, then part of the German Empire.

[2] In 1909 Berg was appointed senior building official in Breslau (now Wrocław, Poland), in Silesia.

His most notable contribution to architecture is the Jahrhunderthalle (Centennial Hall) built between 1911 and 1913 as part of a series of works commemorating the 100th anniversary of the 1813 War of Liberation against Napoleon Bonaparte.

[3] Other works in Breslau (Wrocław) include the market hall (a huge concrete structure of elliptical arches, but appearing more traditional externally) and a large office building on the SW corner of the Main Market Square.

[4] In 1925, the year he retired from his architectural career for Christian mysticism, Berg moved to Berlin and then to Baden-Baden, where he died in 1947, aged 76.
