(John), born at Paris in 1632, was an universal scholar; but chiefly noted for having been, in conjunction with M. de Sallo who formed the plan, the first publisher of the Journal des Savants. The first journal was published January 5, 1665; but these gentlemen criticized new works so rigorously, that the whole tribe of authors united and cried it down. De Sallo declined entirely after the publication of the third number; but Gallois ventured to send out a fourth, on January 4th 1666; though not without a most humble advertisement at the beginning, wherein it was declared, that the author "would not presume to criticize, but simply give an account of the books."

This, with the protection of M. Colbert, who was greatly taken with the work, gradually reconciled the public to it; and thus began literary journals, which have been continued from that time to this, under various titles, and by various writers. Gallois continued his journal to the year 1674, when more important occupations obliged him to turn it over to other hands. M. Colbert had taken him into his house to teach him Latin; and when he lost his patron in 1683, he was first made librarian to the king, and then Greek professor in the royal college. He died in 1707.
