Sheldon Brown (July 14, 1944 - February 3, 2008) was an American bicycle mechanic and technical authority. He maintained an extensive website containing authoritative articles relating to bicycle mechanics and maintenance, as well as a thorough glossary of bicycling terminology. http://sheldonbrown.com/

He was an enthusiast for many old and unlikely forms of bicycles and cycling including Raleigh and their English three-speed cycles, the Sturmey-Archer hub in general, tandems, and in particular fixed-gear cycles. Sheldon Brown also wrote a well-regarded guide to wheelbuilding, available on his website.

In August 2007 Sheldon was diagnosed with primary progressive multiple sclerosis. After losing his ability to balance an upright bicycle to the disease, he was able to continue pedaling by using a recumbent tricycle. Sheldon passed away on February 3, 2008 after a heart attack.
