Donald Humphries co-founded The Touring Cyclist group of bike shops and touring company with Carol Boedeker in 1973 in the St. Louis area of Missouri. The Terranaut house brand sold alongside Fuji, Trek and Marukin. Starting in 1983, the Terranaut Wanderer MTB was introduced and it wouldn't be until 2005 that Terranaut branded another mountain bike, other than some near mtb hybrids.
