Hermann Alexander Diels (German: [diːls]; 18 May 1848 – 4 June 1922) was a German classical scholar, who was influential in the area of early Greek philosophy and is known for his standard work Die Fragmente der Vorsokratiker. Diels helped to import the term Presocratic into classical scholarship and developed the Diels–Kranz numbering system for ancient Greek Pre-Socratic texts.^[1]
