Percy John Daniell

Percy John Daniell (9 January 1889 – 25 May 1946) was a pure and applied mathematician. In a series of papers published between 1918 and 1928, he developed and expanded a generalized theory of integration and differentiation, which is today known as the Daniell scheme.

Daniell was born in Valparaiso, Chile. His family relocated to England in 1895. Daniell completed his university education at Cambridge (where he was the last Senior Wrangler in 1909) and Göttingen. He held university positions at the Rice Institute, Houston, Texas, and later at the University of Sheffield. Daniell also advised the British Ministry of Supply during the second world war. The strain of work during the war took a heavy toll on his health. He died on 25 May 1946, after having collapsed at his home a few weeks earlier.
