Thomas and his son, Samuel, walked into the infant community of
Catasauqua, Pennsylvania, on the Lehigh Coal and Navigation Company's towpath on July 9, 1839. Less than one year later, on July 4, 1840, the first successful anthracite iron furnace in the United States began operation. Thomas's iron works was extremely successful, even though the iron industry in the rest of the Lehigh Valley had begun to decline. The company was incorporated in 1839 as the
Lehigh Crane Iron Company, and in 1872 the name was changed to the Crane Iron Company. By that time the community was no longer known as Craneville, but as Catasauqua; Thomas had named both his company and the town in which he founded it after his former employer in Wales. Iron produced at the Crane Iron Company was used in a number of products, many of which were made elsewhere in Catasauqua. The neighbouring company of John Fritz's Iron Foundry used Crane iron to build the first American-made cast-iron construction columns, while the nearby Davies and Thomas Foundry turned Crane iron into pipes and tunnel tubes. Among the still-existing structures which were created using Crane iron are the
Holland and
Lincoln Tunnels in New York City. Thomas's industry helped the small town to become quite prosperous, and he himself became a wealthy landowner. ==Philanthropy and honors==
