Marc has been a model railroader since he received his first train at age 4. Since then he has modeled in O scale, HO, HOn3, Sn2, 1:20.3, 16mm, and 7/8".
In 1976, Marc formed an architectural graphic design company, Sidestreet Bannerworks. Three years later, he added an importing division to his company, bringing scale live-steam locomotives into the United States from England, Germany, and Japan.
As a way to inform customers about new developments in the small-scale steam hobby, Marc began producing a company newsletter, the Sidestreet Banner. Then, in 1984, he and his wife, Barbara, founded Garden Railways magazine. The magazine was sold to Kalmbach Publishing Company in 1996. Marc stayed on as editor, while Barb retired.
Since starting Garden Railways, Marc and Barb have traveled extensively throughout the U.S. and Great Britain, visiting and documenting a large number of garden lines. They have also built three railways of their own.
