Matthias N. Forney

Matthias Nace Forney (March 28, 1835 – January 14, 1908) was an American steam locomotive designer and builder.

Locomotives that he designed served the elevated railroads of New York City for many years before that system converted to electric power.

He apprenticed with another prominent locomotive builder, Ross Winans, before joining the Baltimore and Ohio Railroad (B&O) as a draftsman in 1855.

At that time, he started working as an associate editor for Railroad Gazette and quickly earned a reputation as an expert in steam locomotive theory.

In late 1886, he bought the rival publication American Railroad Journal, as well as Van Nostrand's Engineering Magazine.
