Johan Ludvig Heiberg (1854-1928) was a distinguished Danish philologist and historian of mathematics, renowned for his groundbreaking work in uncovering lost texts and editing ancient mathematical works. Heiberg's most notable achievement was the discovery of the Archimedes Palimpsest, which contained the only known copy of Archimedes' "The Method." His meticulous editing of works by Euclid, Ptolemy, and other ancient scholars has left an indelible mark on the field of classical studies. Beyond his academic contributions, Heiberg was a professor and a member of the Royal Danish Academy of Sciences and Letters, cementing his legacy as a pivotal figure in the preservation and understanding of ancient mathematical and philosophical texts.
