Bachmann is a German and Swiss surname with a topographic origin. It denoted a person who lived near a stream, derived from Middle High German bach "stream" and man "man". Variants include Bachman, and Low German forms such as Beckman(n) and Beekman(n).Historical OriginsThe surname originates as a description of the bearer's dwelling near a brook (Bach). Early attestations include a farm "Hofstatt am Bach" also called "Bachmanns Hofstatt" near Hinwil or Dürnten in Switzerland, recorded in 1387, and the "Hof zum Bach" near Richterswil, recorded in 1555. The name is thus toponymic, referring to someone who lived on or worked at a farmstead by a stream.Geographical Distribution and Notable LinesIn Switzerland, there are three main lines of Bachmann families.
