Sir Theodore de, baron of Aulbone, was the son of Lewis de Mayerne, the celebrated author of the General History of Spain, and of the Monarchie ariflo-democratique, dedicated to the states-general. He was born in 1573, and had for his godfather Theodore Beza. He studied physic at Montpelier, and was made physician in ordinary to Henry IV. who promised to do great things for him, provided he would change his religion. James I. of England invited him over, and made him first physician to himself and his queen, in which office he served the whole royal family to the time of his death in 1655. His works were printed at London in 1700, and make a large folio, divided into two books; the first containing his Confilia, Epistolae, et Observations; the second his Pharmacopeia variaeque medicamentorum formulae.
