[1] His father, Guillaume Andral (1769-1853), held an honorary membership in the Academy of Medicine and had a career as a surgeon in the French Revolutionary Armies.
[1] In 1828 Andral was appointed professor of hygiene, and in 1839 succeeded François-Joseph-Victor Broussais (1772–1838) as chair of general pathology and therapy, a position he held for 27 years.
With his colleague, Louis Denis Jules Gavarret (1809–1890), he performed extensive studies of blood composition.
Andral's crowning written achievement was Clinique médicale, a five-volume work that discussed almost every facet of medicine known at the time.
Andral is credited as the first physician to describe lymphangitis carcinomatosa, a disease that is usually associated with cancers of the lung, breast, stomach, and cervix.
