Prevear was a silversmith, watchmaker, and inventor. He was born in Northampton (1818) and apprenticed to Samuel Harrington of Amherst, who later became his partner. He married Olive Hanscome in Amherst (1843), and after her death married a second time (1856) to Elizabeth Pranker, an 1853 graduate of Mount Holyoke Female Seminary, now Mt. Holyoke College. Subsequent to the second marriage, he moved to Leominster and continued in business there.
Prevear held the patent for a precisely calibrated meridian-time indicator, and was appointed by Governor Claflin (1870) as commissioner to establish meridian lines in our fair Commonwealth. Judging by the number of items which survive, it is safe to say that silver by this maker is scarce.
