[2]Davis and Gartner have an earlier claim to engineering fame, for in conjunction with John Elgar they had constructed in York, in 1825, the first American-built vessel with a metal hull, the sheet-iron steamboat _Codorus_. [3]Although he spelled his name Gartner, and it appears in that form in the early annual reports of the Baltimore and Ohio Rail Road Co., and in all subsequent histories of that road, his tombstone (in lot 34, section H of the Prospect Hill Cemetery in York, Pa.) bears the name in its Anglicized form, Israel Gardner.
