George Eldridge (November 27, 1821 - August 23, 1900) and his son George Washington Eldridge (1845 - 1914) were American makers of nautical charts and Pilot Books active in the late 19th century. George Eldridge was a Cape Cod fisherman known locally as an excellent ship's pilot. While recuperating from an injury in 1851, Eldridge drew his first nautical chart. The chart proved popular, and its success led Eldridge to pursue a career in hydrography - the science of mapping the sea with a special focus on navigation. Eldridge produced numerous subsequent maps and is credited with issuing some of the earliest accurate nautical charts of the American Atlantic coast. In time George Eldridge passed his thriving business on to his son, George Washington Eldridge, who continued to produce beautiful and practical maritime charts until 1924.Though most of Eldridge's charts were loosely based on U.S. Coast Survey work, they proved popular with navigators. The Eldridges possessed a talent, shared by both father and son, for distilling the often convoluted Coast Survey maps into practical nautical charts for the working mariner. From 1875, in addition to large format independently issued nautical charts, Eldridge also issued annual editions of Eldridge's Tide and Pilot Book and The Book of Harbor Charts. The Eldridge offices were located at 103 State St. Boston, Massachusetts. After the deaths of George and George Washington Eldridge, the firm passed into the hands of the latter's widow Sydna, and son-in-law, Wilfrid O. Wight. Wight's son and subsequent generations have continued to publish the Eldridge Tide and Pilot Book down to the present. More by this mapmaker...

Sydna Eldridge (1846 - 1936) was a hydrographer and publisher of nautical charts active in the mid-1920s, a member of the family of George Eldridge, a noted hydrographer of the late 19th and early 20th century. When George Eldridge died in 1900, the firm passed to his son George Washington Eldridge (d. 1914). Sydna has been noted elsewhere as George Washington Eldridge's granddaughter, born to his daughter and son-in-law Wildred O. White, but U.S. Census records indicate that she was in fact George Washington Eldridge's wife. In any event, in 1914, when George Washington Eldridge died, the firm came to be managed by Wildred O White. For a period in the late 1910s to the mid-1920s, the firm published charts copyrighted to Synda Eldridge but with White listed as publisher, until the last Eldridge charts were published in 1924. However, White's son and descendants have continued to publish annual editions of Eldridge tide and pilot book down to the present. Learn More...
