The Pontifical Academy of Sciences dates back four centuries to its creation as the Accademia dei Lincei in 1603. Pope Pius IX changed the name to the Pontifical Academy of the New Lincei in 1847 to signify its new status as an official institution of the Pontifical State. Nearly a century later, it was reorganized as the Pontifical Academy of Science on October 28, 1936, by Pope Pius XI in a Motu proprio In multis solaciis (Latin "Among the many consolations").
