Charles Hutton (August 14,1737 - January 27, 1823) was an English mathematician. In 1764 he published his first work, The Schoolmasters Guide, or a Complete System of Practical Arithmetic, which in 1770 was followed by his Treatise on Mensuration both in Theory and Practice. In 1773 he was appointed professor of mathematics at the Royal Military Academy, Woolwich, and in the following year he was elected fellow of the Royal Society of London. One of the most laborious of his works was the abridgment, in conjunction with G. Shaw and R. Pearson, of the Philosophical Transactions. This undertaking, the mathematical and scientific parts of which fell to Hutton's share, was completed in 1809, and filled eighteen volumes quarto. He resigned his professorship in 1807 and died in 1823 at the age of 85. This image has been color enhanced.
