Samuel Merrill, a native of Peacham, Vermont, was an early lawyer and leading citizen of Indiana, who served as state treasurer from 1822 to 1834. Merrill attended Dartmouth College, and in 1816 settled in Vevay, Indiana, where he established a law practice and served in the Indiana General Assembly as a representative from Switzerland County (1821–22). Merrill resigned his position as state treasurer in 1834 to become the president of the State Bank of Indiana (1834–44); he also served as the president of the Madison and Indianapolis Railroad Company (1844–48) and head of the Merrill Publishing Company, which later became the Bobbs-Merrill Company. In addition to his government service and business ventures, Merrill was the second president of the Indiana Historical Society (1835–48), a founder and trustee of Wabash College, and an elder in the Second Presbyterian and Fourth Presbyterian churches in Indianapolis.

James Brown Ray was an Indiana politician and the only Indiana Senate president pro tempore to be elevated to governor of the state of Indiana. Ray served during a time when the state transitioned from personal politics to political parties, but never joined a party himself. Taking office one week before his 31st birthday, he became the state's youngest governor and served from 1825 to 1831, the longest period for an Indiana governor under the state constitution of 1816. During Ray's term as governor the state experienced a period of economic prosperity and a 45 percent population increase. He supported projects that encouraged the continued growth and development of the young state, most notably internal improvements, Native American removal, codification of Indiana's laws, improved county and local government, and expanded educational opportunities. Ray was known for his eccentricity and early promotion of a large-scale railroad system in the state. His support for new railroad construction and alleged involvement in several scandals caused him to lose popularity among voters. Ray's opponents who favored the creation of canals considered railroads to be an impractical, utopian idea. Following Ray's departure from political office, he continued to advocate for a statewide railroad system until his death in 1848.
