Thomas and William Collyer
New York NY
Thomas Collyer and William Collyer were brothers who had started in shipbuilding up the Hudson River. In 1844 they went into a partnership, in a shipyard in Manhattan, at the foot of 12th Street. In 1847, however, they dissolved the partnership, with William staying put and Thomas moving to a yard at the foot of 21st Street. Both continued to build ships until the end of the Civil War.
