Oktober 1865greg. in Walk; † 25. Dezember 1921 in Riga) war ein livländischer Mathematiker, der sich mit fastperiodischen Funktionen, Himmelsmechanik und Differentialgleichungen beschäftigte. (de) Piers Bohl, né le 11 octobre 1865 (23 octobre 1865 dans le calendrier grégorien) à Walk et mort le 25 décembre 1921 à Riga, est un mathématicien live qui a travaillé sur les fonctions presque périodiques, la mécanique céleste et les équations différentielles. (fr) Piers Bohl (23 October 1865 – 25 December 1921) was a Latvian mathematician, who worked in differential equations, topology and quasi-periodic functions. He was born in 1865 in Walk, Livonia, in the family of a poor Baltic German merchant. In 1884, after graduating from a German school in Viljandi, he entered the faculty of physics and mathematics at the University of Tartu. In 1893 Bohl was awarded his Master's degree. This was for an investigation of quasi-periodic functions. The notion of quasi-periodic functions was generalised still further by Harald Bohr when he introduced almost-periodic functions. He has been the first to prove the three-dimensional case of the Brouwer fixed-point theorem, but his work was not noticed at the time.

Hij werd in 1865 in Valka, Lijfland geboren in het gezin van een arme Baltisch Duitse handelaar. Na in 1884 te zijn afgestudeerd aan een Duitse school in Viljandi ging hij wis- en natuurkunde studeren aan de Universiteit van Tartu. In 1893 behaalde Bohl zijn doctoraat.
