He was born in Athol, Massachusetts. Some references list his actual birth date as August 22, 1811 (Waters, p. 43), while others list it as August 26, 1811 (Congress Bioguide; and Massachusetts Vital Records).[1] In 1827 Twichell left school to seek employment in a local mill. Subsequent jobs saw him working with livestock and later in retail. His strengths in transportation began to show in 1830 when he took control of a stage line between Barre and Worcester.
As a manager and business owner, Twichell gained a reputation for kindness and generosity, even toward his business competition. He saw his stage line grow to include many more lines throughout New England. When the Boston and Worcester Railroad (B&W) opened on July 1, 1835, Twichell's stage lines were both competition and complement to the railroad's service. This quasi-partnership lasted until June 1, 1848, when Twichell became the assistant superintendent of the railroad. Twichell rose through the B&W's ranks, becoming president in 1857.
In 1867 Twichell was elected to Congress where he served as a Republican Representative for Massachusetts. He was twice reelected, in 1869 and again in 1871, to stretch his tenure to three consecutive terms.
