Henri Louis Francois Marindin. 

 1843-1904. 



Mr. Marindin was born at Lausanne, Switzerland, July 2, 

 1843, and received his early education in the Swiss schools. 

 He came to the United States before attaining manhood, and 

 finished his scholastic education in the Owego Academy at 

 Owego, New York, 1860-1863. 



He entered the Coast Survey as aid on November 26, 1863, 

 and was soon assigned to duty in a party engaged in the survey 

 of Roanoke River, North Carolina, made at the special request 

 of Admiral S. P. Lee, flag officer of the North Atlantic block- 

 ading squadron, the party being quartered on the gunboat Sey- 

 mour for that purpose. In 1864 he served in a topographic 

 party at work in the vicinity of Bermuda Hundred, Virginia, 

 under the orders of Major General Butler, with Brigadier 

 General Weitzel in immediate charge of the work, and later in 

 the same year, and in January, 1865, he served in a topographic 

 party engaged in work along the Potomac River under the 

 direction of Major C. S. Stewart. He thus began his service 

 to the nation of his adoption by aiding in the perpetuation of 

 the Union, and continued to serve his country faithfully until 

 death ended his long and honorable career. 



In 1865 he was engaged in special surveys for a canal route 

 through Nicaragua, and in 1870 he was engaged in similar 

 work on the Isthmus of Darien. 



His special work in the Coast Survey was in the field of 

 physical hydrography, and man}'^ important features in the cur- 

 rents and in the development of harbors and bars along the 

 Atlantic and Gulf coasts of the United States have been made 

 known to commerce as the result of his systematic and careful 

 investigation of the complex problems presented as the result 

 of the action of winds and tides on the waters of the sea. He 

 spent more than eighteen years in command of vessels of the 

 Survey while engaged in this work.
