Ingeborg Hammer-Jensen (Copenhagen, 20 January 1880 - Copenhagen, 6 April 1955) was a historian of science and classical philologist from Denmark. She was the third woman to be awarded a PhD in Denmark and was an expert on Greek scientific writing.

Early life

Ingeborg Ellen Hammer was born on 20 January 1880 in Copenhagen. Her parents were choir director and herbalist Axel Evald Hammer, and her mother was Thora Christine Svendsen. She attended N. Zahle's School, where she learnt Mathematics and Greek, amongst other subjects, where she got excellent marks.

Education

In 1898 she began to study classical philology at the University of Copenhagen, where she was inspired by the work of Professor J L Heiberg and H G Zeuthen to research the scientific writings of classical writers. Her first article was published in 1902 in the Nordic Journal of Classical Philology. In 1905 she graduated with an MA in Classical Philology.

Hammer-Jensen continued her research and in 1908 graduated with a D.Phil. in Classical Philology from the University of Copenhagen. Her thesis was entitled The Oldest Atomic Theory and argued that Plato was influenced by Democritus' natural theory. Whilst this idea was not entirely original, Hammer-Jensen's work became influential because she promoted her ideas with energy. She was the first female recipient of a doctorate in Classics in Denmark, and the country's third female PhD overall (preceded by Anna Hude in 1893 and Kirstine Thaning in 1904).

Research

Hammer-Jensen's research focused on science in the classical world, particularly the works of Aristotle, Democritus and Heron. Her critique of Aristotle's Metereology IV argued against it being Aristotelian in origin and is one that has been cited repeatedly. She wrote about potential relationships between the work of Democritus and Plato. She worked on dating the works of Heron to after the time of Ptolemy, basing this assertion on Heron's apparently superior scientific instruments and a potential criticism of Ptolemy's views on weight and volume relating to water. Her doctoral thesis advanced the idea that Democritus influenced Plato, and gained a substantial amount of attention after its publication.

In her later work The Oldest Alchemy, Hammer-Jensen examined the works of writes Zosimos, Olympiodor and Stephanos to explore ideas around the transition of materials from one form to another. However, one reviewer described her work as "fanciful". In it she emphasised a close relationship between medicine and alchemy, based on their experimental processes. However this idea was criticised by others who believed the awareness of medicine shown by these authors was what would be expected by an educated person at the time.
