Johann Heinrich Lambert

Died 25 Sep 1777 at age 49 (born 26 Aug 1728). Swiss-German mathematician, astronomer, physicist, and philosopher who provided the first rigorous proof that pi is irrational (cannot be expressed as the quotient of two integers). In 1766, Lambert wrote Theorie der Parallellinien, a study of the parallel postulate. By assuming that the parallel postulate was false, he deduced many non-euclidean results. He noticed that in this new geometry the sum of the angles of a triangle increases as its area decreases. Lambert conjectured that e and p are transcendental, though this was not proved for another century. He is responsible for many innovations in the study of heat and light, devised a method of measuring light intensity, as well as working on the theory of probability.
