John Forester (cyclist)

John Forester (7 October 1929 – 14 April 2020) was an English-American industrial engineer, specializing in bicycle transportation engineering. As cycling activist, he was known as "the father of vehicular cycling", for creating the Effective Cycling program of bicycle training along with its associated book of the same title, and for coining the phrase "the vehicular cycling principle" – "Cyclists fare best when they act and are treated as drivers of vehicles". His published works also included Bicycle Transportation: A Handbook for Cycling Transportation Engineers.

His works have come under criticism for posturing personal preference as fact, for strongly influencing American traffic engineering in the 1980s against building dedicated cycling infrastructure, and for ignoring peer-reviewed research around cyclist fatality rates on roadways when comparing dedicated cycling infrastructure against vehicular cycling.
