Oskar Bolza

Died 5 Jul 1942 at age 85 (born 12 May 1857).German mathematician who moved to the U.S. in 1888. He published The elliptic s-functions considered as a special case of the hyperelliptic s-functions in 1900. From 1910, he worked on the calculus of variations. Bolza wrote a classic textbook on the subject, Lectures on the Calculus of Variations (1904). He returned to Germany in 1910, where he researched function theory, integral equations and the calculus of variations. In 1913, he published a paper presenting a new type of variational problem now called "the problem of Bolza." The next year, he wrote about variations for an integral problem involving inequalities, which later become important in control theory. Bolza ceased his mathematical research work at the outbreak of WW I in 1914.«
