## Early life and family

Richard Henry Rice was born January 9, 1863, in Rockland, Maine, to Albert Smith Rice and Frances Weston (Baker) Rice. He received his Masters of Engineering degree from Stevens Institute of Technology in 1885. He was first married on April 6, 1887, to Mary Sue Durgin, daughter of William B. Durgin, a silversmith and clock-maker from Concord, New Hampshire, and they had three children. After the 1897 death of his first wife, Rice married Alice Woodman Kimball of New York March 26, 1898.

## Engineering career

Rice began his engineering career in 1885 heading the testing laboratory at Stevens Institute. From 1885-1886 he was a special apprentice at the Pittsburgh, Cincinnati, Chicago and St. Louis Railroad shops in Dennison, Ohio. From 1886-1887 he was a designer of marine engines at the Bath Iron Works in Bath, Maine.

In 1894, he was an incorporating officer in the Rice & Sargent Engine Company, and he served as treasurer of the company. Rice and Sargent steam engines were used extensively for power plants in manufacturing companies from the mid-1890s to the 1930s. Rice was also an owner of the Providence Engineering Works, also in Providence. Starting in 1903 he was a consultant on steam engineering and in charge of turbine development at the General Electric Company in Lynn, Massachusetts. In recognition of over 50 patents relating to steam, air and water apparati, he received an honorary Ph.D. in Engineering from the Stevens Institute in 1921. He died a year later on February 10, 1922, in Bolton, New York.
