He founded the field of nomography, the graphic computation of algebraic equations, on charts which he called a nomogram. == Biography == Philbert-Maurice Ocagne was born in Paris on 25 March 1862. He attended high school at the Lycée Fontanges school in Paris, and studied at Chaptal college. In 1877, he published his first mathematical work. In 1880, he entered the École Polytechnique. He published many articles on math. Starting in 1885, he served for six years as engineer, supporting waterworks projects in Rochefort and Cherbourg, then worked at Seine-et-Oise, at the residence of Pontoise. From 1882, continued to published articles on mathematics in the Academy of Sciences.
