Background
He was the son of the humanist Gerhard Johann Vossius.
Librarian musicologist philologist theorist
He was the son of the humanist Gerhard Johann Vossius.
Isaak formed what was accounted the best private library in the world (Massil 2003). He had a contemporary reputation for eccentricity, refusing the sacrament on his deathbed, it was reported, until reminded that to do so would reflect unfavorably on the canons of Street George"s Chapel, Windsor Castle, to which chapter he belonged. He was raised in the atmosphere of a scholarly household, familiar with Greek, ancient geography, and Arabic from an early age.
That year he was elected a Fellow of the Royal Society in London.
In 1648, he went to Sweden, summoned by Queen Christina to take up a position as her court librarian, and was accompanied by Cornelius Tollius as his amanuensis. There he enriched the library that had been founded by Gustavus Adolphus, partly as booty of war from the library of Prague, with judicious purchases, but incurred the enmity of the French philologist Claudius Salmasius.
At the death of his father in 1650, he returned briefly to Amsterdam to oversee the shipping of his father"s library to Stockholm. The impecunious queen paid her former librarian"s outstanding back pay in books, among which was the Codex Argenteus.
After his brilliant, though at times controversial, career of scholarship in Sweden, Vossius went to England in 1670, received a degree in civil law from Oxford, and became residentiary canon at Windsor in 1673, a post he held until 1688, shortly before his death.
In the later stage of his life, his interests turned to mathematics and natural history. After his death, his heirs sold his library of books and manuscripts to the University of Leiden.
