hoist rope. The next year Otis resigned from his job and
set up a small elevator shop in Yonkers, selling his first
elevator machine on Sept. 20, 1853. It hauled freight.
Orders were few until May 1854, when, at the Crystal
Palace in New York City, he demonstrated his elevator by
riding the platform high in the air and ordering the rope
cut. On March 23, 1857, he installed the first safety elevator
for passenger service in the store of E.V. Haughwout &
Co. in New York City; driven by steam power, it climbed
five stories in less than a minute and was a pronounced
success. On Jan. 15, 1861, Otis patented an independently
controlled steam engine for elevator use (installed in 1862).
This invention laid the foundation for the business that
his two sons, Charles and Norton, carried on after his
death as owners of what eventually became the Otis
Elevator Company.
Otis also devised a number of other mechanical con-
trivances. In 1852 he patented some railroad-car trucks
and brakes. In 1857 he patented a steam plow, and in 1858
he patented a bake oven.

ir Henry Bessemer was an English inventor and engi-

steel inexpensively (1856), leading to the development of
the Bessemer converter. He was knighted in 1879.
Bessemer was the son of an engineer and typefounder.
He early showed considerable mechanical skill and inventive
powers. After the invention of movable stamps for dating
deeds and other government documents and the improve-
ment of a typesetting machine, he went to the manufacture
of “gold” powder from brass for use in paints. The florid
