Jacamiah Seaman Daugherty, entrepreneur and land dealer, the son of Robert W. and Lydia E. Seaman (Bryan) Daugherty, was born in Sullivan County, Missouri, on August 25, 1849. He attended the University of Kentucky for three years before moving to Texas in 1872. He taught school for a year at the Cedar Hill district school in Dallas and in 1873 opened a real estate office that expanded to become the firm of Daugherty, Connellee, and Ammerman, which had large holdings in Eastland County. The firm was instrumental in laying out Eastland and in making the new community the Eastland county seat in place of Merriman. In 1879 the Texas Trunk Railroad built a depot named for Daugherty on land he had purchased and improved in Kaufman County.
In 1888 Daugherty organized what may have been the first real estate association in Texas and the Texas Bureau of Immigration. He also obtained contracts to supply thirteen United States military posts in Texas with grain and hay obtained from Texas, Oklahoma, and Kansas. When the crop failed, financial reversals took him to Houston, where he developed mineral resources and real estate. In 1894 he acquired 6,000 acres in Harris County, provided a right-of-way and obtained a siding for the San Antonio and Aransas Pass Railway, founded Dairy (later Alief, TX), and introduced the production of rice there.
Daugherty was active in the conflict over requiring Texas cattlemen to pay rent to the public school fund for school lands used in grazing cattle, the conflict that led to the formation of the Railroad Commission, and the effort to require banks to provide funds to protect depositors against loss. His Silver Day speech delivered at the Chicago World's Fair in 1893 became campaign literature for advocates of free silver. He is credited with the idea for the "business league" and served as chairman of the first league in Dallas from 1882 to 1888. From 1890 to 1895 he promoted efforts of the Good Roads Committee and by 1909 was chairman of the Harris County Drainage District and active in working for a deep-water harbor at Galveston. Daugherty married Margaret Cartmell Bryan on December 19, 1878; the couple had at least three children. He died in a railway-crossing accident at Fulton, Kentucky, on September 27, 1919.
