Justin Marie Jolly

Justin Marie Jolly (August 6, 1870 – 1953) was a French physician known for his work in haematology. He studied medicine at the Collège de France under Louis-Antoine Ranvier (1835-1922) and Louis-Charles Malassez (1842-1909) where he learned histological techniques and their correlation to other medical disciplines.

He was a pioneer in the field of haematology as it pertained to the study of living tissue. In the early- 20th century he produced the earliest films of mitosis in living cells via microscopic movies. In 1923, he published an influentual textbook on haemotology. Along with American physiologist William Henry Howell (1860-1945), the Howell-Jolly bodies are named; which are 1-2 µm granules seen in erythrocytes (red-blood cells).
