Alvin Adams was born on June 16 1804 in Andover, Vermont. On May 4 1840 he established his first express freight route between Boston and New York under the name Adams and Company. The company established offices in Boston and New York, and soon added express routes to Baltimore, Maryland, Norwich, Connecticut, Worcester, Massachusetts, Washington, D.C., Pittsburgh, Pennsylvania, Cincinnati, Ohio, Louisville, Kentucky, and St. Louis, Missouri. Adams and Company started out by hauling mail for the nascent postal service, until that business was suspended by the US Government in 1845; in that year the transportation of mail was transferred to solely government-owned entities.
In 1854 Adams and Company merged with three other express agencies, Harnden and Company, Thompson and Company, and Kinsley and Company to form Adams Express Company, with Mr. Adams as the president of the new company. The company was initially capitalized with $1,200,000. He was succeeded in 1855 by George W. Cass.
Alvin Adams died September 1 1877 in Watertown, Massachusetts. The company that he formed still exists, headquartered in Baltimore, Maryland.
