James Jay Mapes (May 29, 1806 – January 10, 1866) was an American chemist, inventor and educator, mostly known for his achievements in scientific agriculture.
Mapes was born in New York on May 29, 1806. His father, Jonas Mapes, was a major-general in command of the New York state forces in and around New York in the year 1812. Nearly all his ancestors on the father's side were farmers on Long Island, back to 1640, when Thomas Mapes came from England and settled there. In his early years, James showed passion for chemistry, invention and military matters. From the age of 11, for a few years, he studied at the classical school of Timothy Clowes at Hempstead, Long Island, while living with renowned English reformer William Cobbett. When only seventeen years of age he delivered a full course of lectures in New York on "Military Tactics".
Later Mapes became known as an analytical chemist, and his analyses of beer and wines, made at requests of the senate of New York and the temperance societies, were regarded as standard experiments. He was one of the first manufacturer of magnesium sulfate from magnesium hydrobisilicate and the author of many improvements in tempering steel, distilling, dyeing, and other areas. In 1832 he invented a new system of sugar refining and later an apparatus for manufacturing sugar from the cane. He was the inventor of processes for tanning leather and the manufacture of sugar from West India molasses. He also designed a centrifugal machine for separating molasses from sugar.
Soon after the organization of the National Academy of Design in New York he was appointed professor of chemistry and natural philosophy to that institution. Subsequently, he was appointed professor of chemistry and natural philosophy to the American Institute. In 1844 he was elected president of the Mechanics' Institute of New York. He was one of the founders of the National Agricultural Society, and held the position of vice-president of the American Institute, with which he had been actively connected for at least 25 years. He was made a permanent member of the New York Lyceum of Natural History, and of the National Institute at Washington, and an honorary member of the Scientific Institute of Brussels, Royal Society of Saint Petersburg, Geographical Society of Paris, Artists' Fund Society of Philadelphia, and several horticultural and agricultural societies of Europe and America.
