absorb all of his energy, however. He became active in
the Democratic Party and in the Presbyterian Church,
establishing the McCormick Theological Seminary in
Chicago.
In 1871 the Chicago Fire gutted his factory. Then—
more than 60 years old, his fortune long since made—he
rebuilt. When he died, his business was still growing. In
1902 the McCormick Harvesting Company joined with
other companies to form International Harvester Company,
with McCormick’s son, Cyrus, Jr., as its first president.

England to New England in 1631, the young Otis grew up
in Vermont and, at age 19, moved to Troy, N.Y., and later to
Brattleboro, Vt., working at various jobs. From 1838 to 1845,
in Brattleboro, he manufactured wagons and carriages and
then moved his family to Albany, N.Y., where, while
employed as a master mechanic in a bedstead factory, he
invented several labour-saving machines. In 1851 he was
in Bergen, N.J., again as master mechanic in a bedstead
factory. The Bergen firm sent him to Yonkers, N.Y., in 1852
to operate a new factory and to install its machinery. There
he designed and installed what he called the “safety hoist,”
the first elevator equipped with an automatic safety device
to prevent it from falling if the lifting chain or rope broke.
Prior to this invention, the poor reliability of the ropes
(generally hemp) used at that time made lifting platforms
unsatisfactory for passenger use. Otis’s device incorporated
a clamping arrangement that gripped the guide rails on
which the car moved when tension was released from the
