Jobst Brandt (January 14, 1935 – May 5, 2015) was an American mechanical engineer, inventor, bicycle enthusiast, educator, and author.

[3] After two years of military service in the US Army Corps of Engineers, stationed near Frankfurt, Germany, he found employment at Porsche.

[4] His subsequent employers included Hewlett Packard, SLAC National Accelerator Laboratory, and Avocet, a bicycle accessories brand.

From the late 1980s until the early/mid 2000s, the era of the Usenet newsgroup, Jobst Brandt was a prolific contributor to rec.bicycles.tech and other public forums.

[6][7] His authoritative explanations and incisive, sometimes tart opinions on bicycle technology, as well as the detailed descriptions of his inspiring bike holidays in the Alps[8] and epic one-day rides in the Santa Cruz Mountains,[9] brought him a wide readership among avid bicyclists well beyond the Bay Area, in the nascent online community.
