In the first decade of the 20th century, Henri Lebesgue developed a new approach to integral calculus in order to overcome the restrictions of previous theories. At that time, integration was used to calculate the area under a curve, but if the curve...

Lebesgue was born in Beauvais, France, and received his undergraduate college training in mathematics at the École Normale Supérieure in Paris. While teaching at the Lycée Centrale in Nancy, France, Lebesgue worked on his doctoral...

1875-1941 French Mathematician Like many another mathematical innovator, Henri Lebesgue was not immediately recognized for his principal achievement, in his case a new approach to integral calculus. As so often happens with groundbreaking ideas, his...

Henri Lebesgue (1875-1941) revived the troubled field of integration. His generalization of integration, and the complex theory of measure he introduced to accomplish this, countered the criticisms and challenges to the field that threatened it at the...

Henri Léon Lebesgue [ɑ̃ʁiː leɔ̃ ləˈbɛg] (June 28, 1875, Beauvais – July 26, 1941, Paris) was a French mathematician, most famous for his theory of integration. Lebesgue's integration theory was originally published in his dissertation,...

THE CALCULUS GALLERY: Masterpieces from Newton to Lebesgue WILLIAM DUNHAM Just as students of music study the symphonies of Beethoven and Bach, people learning calculus should review the proofs, theorems, and definitions composed by the field's masters, Dunham proposes. Beginning with the...

Illustrated by BB Sams Day after day, the dragon of Albertville bellowed and roared. Night after night, he growled and grumbled. The people in the nearby town found it hard to work and even harder to sleep. They started to complain. Finally...
