Justus Friedrich Karl Hecker (5 January 1795, Erfurt – 11 May 1850, Berlin) was a German physician and medical writer, whose works appear in medical encyclopaedias and journals of the time. He particularly studied disease in relation to human history, including plague, smallpox, infant mortality, dancing mania and the sweating sickness, and is often said to have founded the study of the history of disease.
His father August Friedrich Hecker (1763–1811) was also a physician. In 1805, when Justus was 10, the family moved from Justus's birthplace of Erfurt to Berlin, and Justus later studied medicine at the University of Berlin, graduating in 1817 and becoming a Privatdozent and then (in 1822) Extraordinary Professor. In 1834, he became the university's "ordinary professor" for the History of Medicine. He also cooperated with the professors of the "Medical Faculty of Berlin" on the encyclopaedic dictionary of the medical sciences.
Justus (sometimes Iustus; died on 10 November between 627 and 631) was the fourth Archbishop of Canterbury. He was sent from Italy to England by Pope Gregory the Great, on a mission to Christianize the Anglo-Saxons from their native paganism, probably arriving with the second group of missionaries despatched in 601. Justus became the first Bishop of Rochester in 604, and attended a church council in Paris in 614.
Following the death of King Æthelberht of Kent in 616, Justus was forced to flee to Gaul, but was reinstated in his diocese the following year. In 624 Justus became Archbishop of Canterbury, overseeing the despatch of missionaries to Northumbria. After his death he was revered as a saint, and had a shrine in St Augustine's Abbey, Canterbury.
Justus was an Italian and a member of the Gregorian mission sent to England by Pope Gregory I. Almost everything known about Justus and his career is derived from the early 8th-century Historia ecclesiastica gentis Anglorum of Bede. As Bede does not describe Justus' origins, nothing is known about him prior to his arrival in England. He probably arrived in England with the second group of missionaries, sent at the request of Augustine of Canterbury in 601. Some modern writers describe Justus as one of the original missionaries who arrived with Augustine in 597, but Bede believed that Justus came in the second group. The second group included Mellitus, who later became Bishop of London and Archbishop of Canterbury.
