Justus Wilhelm Martin Radius (14 November 1797, in Leipzig – 7 March 1884, in Leipzig) was a German pathologist and ophthalmologist.
He obtained his medical doctorate in Leipzig in 1821, then furthered his education in Vienna, Berlin, London and Paris. In 1825 he became an associate professor for pathology in Leipzig, and in the meantime performed duties as a "free-lance" eye physician. In 1840 he was appointed professor of pathology, hygiene and pharmacology.
In Leipzig, he also served as a physician at St. Georg Hospital (1825–53), and in 1843, following the death of Johann Christian August Heinroth, he was given additional duties as a "part-time chair" of psychiatry. From 1829 to 1861, he was director of the Medizinischen Gesellschaft zu Leipzig.
In 1887 a new building for the Leipzig Conservatory was constructed by way of a donation from Radius. In 1910, the Radiusstraße, a thoroughfare in the Lindenau district of Leipzig, was named after him and his wife, Wilhelmine.
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.
