From the Brooklyn Eagle of November 15, 1881: Daniel Barnum, an old and well known citizen, died of heart disease at his residence in this city yesterday at the advanced age of 83 years. In his earlier manhood he was largely interested in the manufacture of iron in Connecticut and New York, but having developed great inventive genius he abandoned regular business pursuits and devoted his life to the invention of life and labor saving appliances covering the whole field of steam engineering and mining, manufacturing and sewing machinery. As early as 1845 Congress made appropriations for testing and applying his inventions to the Naval service. About the year 1855 he built the steamboat Economy, to demonstrate the advantages of his improvements in compound engine and ran her between New York and Coney Island, landing at what is now Norton’s Point. His inventions led to prolonged and hardly fought litigations, in which he disputed with Woodworth the latter’s claims to the planing machine and with Burr and Wells the originality of invention in the hat body forming machine. Both resulted in compromises after much had been done in settling the rules of law and practice in patent cases. For many years the deceased was a leading expert in patent causes and was associated from time to time with all the patent lawyers of national reputation in the most important cases in this country. He leaves an aged widow, three daughters and three sons, Isaac W. Barnum and Edmund B. Barnum of this city and the Rev. F. S. Barnum of the Westchester Presbytery.
