Russell Benjamin Harrison (August 12, 1854–December 13, 1936), also known as Russell Lord Harrison, was a businessman, lawyer, diplomat, and politician. Harrison was the son of United States President Benjamin Harrison and Caroline Harrison.

Life
Born in Oxford, Ohio, Harrison grew up in Indianapolis, Indiana where his father had a successful law practice. Harrison graduated from the Pennsylvania Military Academy and in 1877 graduated from Lafayette College where he took courses in mining and engineering. In 1878, his grandfather John Scott Harrison was exhumed from his grave and hung by his neck in tree near the Ohio Medical College. Harrison oversaw communication with newspapers during the incident.^[1]

At the end of 1878 he moved to Helena, Montana where he took a job in the U.S. Assay Office with the help of his father who was then a United States Senator. During his time there, he met and married Mary Saunders, the daughter of Governor Alvin Saunders on January 10, 1884. The couple had two children, William Henryand Marthena. In 1885 the family moved briefly to New York City, but had returned to Montana by 1890 when Harrison purchased the Helena Daily Journal. He became estranged from his father following his father's remarriage to a much younger woman, his first cousin Mary Scott Lord Dimmick, but inherited a large part of his estate when he died in 1901.^[1]

Using the wealth, he invested in the Austin and Northwestern Railway, public transportation systems in Richmond and Muncie, Indiana, and engaged in land speculation in Montana. In 1894, Harrison moved to Terre Haute, Indiana as president of the Terre Haute Street Railway Company, which he reorganized into the Terre Haute Electric Street Railway Company. His son William was born in Terre Haute in 1896. During the late 1890s, he was admitted to the bar.

With the outbreak of the Spanish-American War he enlisted for service and was commissioned as a major. He served in the force that occupied Puerto Rico and later became inspector general of Puerto Rico. When the war ended he moved his family to Indianapolis where he set up a law office.^[1]

Due to his service in the Spanish-American War, as well as his descent from President and Major General William Henry Harrison, Harrison became a companion of the Military Order of Foreign Wars.

In 1908 he returned to public service, serving as consul to Mexico until 1927, and doubling as the consul to Portugal from 1919 to 1927. He first entered politics in 1921, serving two two-year terms in the Indiana House of Representatives. In 1925 he was elected to the Indiana State Senate where he served two four year terms. He died of a heart attack in Indianapolis on December 13, 1936.
