Henry Disston & Sons.

Henry Disston & Sons, Inc., was a major manufacturer of saws and other woodworking tools and one of the largest industries in Philadelphia.

Henry Disston, the founder of the firm, was born in Tewkesbury, Gloucestershire, in 1819 and emigrated with his father to Philadelphia in 1833. His father died soon after, and Henry was apprenticed to Lindley, Johnson & Whitcraft, saw manufacturers. The firm failed in the depression in 1840, and young Disston took the tools and stock in lieu of back wages and established his own shop. Disston introduced the Sheffield practice of using crucible steel with the assistance of skilled workers imported from the Sheffield district. Disston produced the first crucible saw steel manufactured in the U.S. in 1855. A rolling mill was added in 1862.
