The surname Krumlauf originated in the German-speaking regions of central Europe during the late medieval period. The name is derived from the Middle High German words "krum" meaning "crooked" or "bent" and "louf" meaning "path" or "course."

One of the earliest recorded instances of the Krumlauf name appears in a 14th-century document from the town of Rothenburg ob der Tauber in Bavaria. Here, a certain Hans Krumlauf is mentioned as a landowner and farmer. The name also crops up in various records from other parts of southern Germany and Austria during the 15th and 16th centuries.
In the 1600s, the surname Krumlauf can be found in church registers and tax rolls from villages around Nuremberg and Bamberg. During this era, the spelling variations Krumlaufer, Krumlauff, and Krumloeffer were also used. A notable bearer was Johannes Krumlauf (1592-1670), a master baker celebrated for his skill in creating ornate gingerbread designs.
By the 18th century, the Krumlauf name had spread more widely across the German states. Christoph Krumlauf (1712-1789) was a respected clockmaker from the town of Schney, while Johann Krumlauf (1734-1807) gained renown as a composer and organist in Memmingen. Records also show Krumlaufs living in Prussia, Saxony, and other areas.
