Jeptha Homer Wade (August 11, 1811 – August 9, 1890) was an American industrialist, philanthropist, and one of the founding members of Western Union Telegraph. Wade was born in Romulus, New York, the youngest of nine children of Jeptha and Sarah (Allen) Wade. He made the first Daguerreotypes west of New York, was a portrait painter, and moved to Adrian, Michigan in 1840 before developing an interest in the telegraph.
In 1847, he was subcontractor for J.J. Speed and constructed a telegraph line from Detroit to Jackson, Michigan, where Wade and his son operated the telegraph office. He also connected Detroit to Buffalo, Cleveland to Cincinnati (Cleveland and Cincinnati Telegraph Company, the Wade Line), and others.
Wade moved to Cleveland, Ohio in 1856 and built a mansion on Euclid Avenue along Millionaires' Row. He and his family also commissioned the Cleveland firm of Hubbell & Benes to design several residences, commercial and public buildings.
In 1856 he helped Hiram Sibley consolidate most of the telegraph industry by forming Western Union through a series of acquisitions and mergers.  In 1861, Jeptha Wade joined forces with Benjamin Franklin Ficklin and Hiram Sibley to form the Pacific Telegraph Company. The company's formation completed the linkage between the east and west coast of the United States by telegraph. Wade became president of Western Union in 1866. A year later he resigned because of ill-health and sold his interests to Jay Gould. He was nominated by the Democratic Party for Representative of Ohio's 18th congressional district in 1864, but lost. He was an incorporator of the Cleveland Rolling Mill Company and the Citizens Savings and Loan Association (becoming its first president), became president of National Bank of Commerce, and served on the board of directors of eight railroads.
Wade used his vast wealth to benefit the city of Cleveland. In 1882, he donated 63 acres (250,000 m2) of land east of the city for the purpose of creating Wade Park, which was named in his honor. Wade Park is Cleveland's cultural center surrounded by the Cleveland Museum of Art, the Cleveland Museum of Natural History, the Western Reserve Historical Society and the Cleveland Botanical Garden.
Wade also was heavily involved with the establishment of Hathaway Brown School, a private academy for young girls and women. He also co-founded the Case School of Applied Technology, part of Case Western Reserve University. In addition, Wade served as the first President of the Board of Trustees for Lake View Cemetery on Cleveland’s east side.
Wade married Rebecca Louiza Facer in 1832, who bore his first son, Randall Palmer Wade, later that year. Rebecca Wade died November 30, 1836 at the age of 24. He re-married in 1837 to Susan Maranda Fleming, with whom they adopted 4 more children. All are buried in Lake View Cemetery, Cleveland.
Wade's grandchildren included Jeptha Homer Wade II (1857-1926), son of Randall Palmer Wade and Anna Rebecca McGaw Wade. He worked in the telegraph industry, banking industry, railway business, mining industry, and manufacturing after graduating from Mt. Pleasant Academy in Ossining, New York and Western Reserve University. He owned the USS Wadena (SP-158). He established the family's Mill Pond Plantation in Thomasville, Georgia in 1906 (later divided by the family to include the Arcadia Plantation). Wade the II bequeathed the Cleveland Natural History Museum a large gem collection now part of the The Jeptha Homer Wade II Gallery of Gems and Jewels. 
Another of the family's Jeptha H. Wades (December 26, 1924 - August 8, 2008) was a prominent Boston attorney who assisted in the formation of the federal Arms Control and Disarmament Agency.
