Pope Leo III
Pope Leo III (died 12 June 816) was bishop of Rome and ruler of the Papal States from 26 December 795 to his death. Protected by Charlemagne from the supporters of his predecessor, Adrian I, Leo subsequently strengthened Charlemagne's position by crowning him emperor. The coronation was not approved by most people in Constantinople, although the Byzantines, occupied with their own defenses, were in no position to offer much opposition to it. Rise According to the '' Liber Pontificalis'', Leo was "of the Roman nation, the son of Atzuppius" (''natione romanus ex patre Atzuppio''). The ''Chronicon Anianense'' says, more specifically, that he was "born in Rome to Asupius and Elizabeth" (''natus rome ex patre asupio matre helisabeth''). Usually considered to be of Greek origin, his father's name may suggest an Arab background.T. F. X. Noble (1985), The Declining Knowledge of Greek in Eighth- and Ninth-Century Papal Rome", ''Byzantinische Zeitschrift'', 78(1): 59. An earlier person o ...

Leo III (or Leon III) hy, Լեւոն Գ, ''Levon III'') (occasionally numbered Leo IV; (1289–1307) was a young king of the Armenian Kingdom of Cilicia, ruling from 1303 or 1305 to 1307, along with his uncle Hethum II. A member of the Hethumid dynasty, he was the son of Thoros III of Armenia and Margaret of Lusignan, who was the daughter of King Hugh III of Cyprus.

Leo A
Leo A (also known as Leo III) is an irregular galaxy that is part of the Local Group. It lies 2.6 million light-years from Earth, and was discovered by Fritz Zwicky in 1942. The estimated mass of this galaxy is solar masses, with at least 80% consisting of dark matter. It is one of the most isolated galaxies in the Local Group and shows no indications of an interaction or merger for several billion years. However, Leo A is nearly unique among irregular galaxies in that more than 90% of its stars formed more recently than 8 billion years ago, suggesting a rather unusual evolutionary history. The presence of RR Lyrae variables shows that the galaxy has an old stellar population that is up to 10 billion years in age. The neutral hydrogen in this galaxy occupies in a volume similar to its optical extent, and is distributed in a squashed, uneven ring. The galaxy is not rotating and the hydrogen is moving about in random clumps. The proportion of elements with higher atomic numbers th ...

LEO III (computer)
The LEO I (Lyons Electronic Office I) was the first computer used for commercial business applications. The prototype LEO I was modelled closely on the Cambridge EDSAC. Its construction was overseen by Oliver Standingford, Raymond Thompson and David Caminer of J. Lyons and Co. LEO I ran its first business application in 1951. In 1954 Lyons formed LEO Computers Ltd to market LEO I and its successors LEO II and LEO III to other companies. LEO Computers eventually became part of English Electric Company (EEL), (EELM), then English Electric Computers (EEC), where the same team developed the faster LEO 360 and even faster LEO 326 models. It then passed to International Computers Limited (ICL) and ultimately Fujitsu. LEO series computers were still in use until 1981. Origins and initial design J. Lyons and Co. was one of the UK's leading catering and food manufacturing companies in the first half of the 20th century. In 1947, they sent two of its ...
