His son, George W. Eldridge, continued on the family business publishing sea charts of the Atlantic seaboard. His most well-known book, the Tide and Pilot book first published in 1854, is often referred to as the "Mariner's Bible" and still in use today, with updated versions published annually.<br/> <br/>
