Alexander Cruden, author of the "Concordance " to the Bible, born in Aberdeen, Scotland, May 31, 1701, died in London, Nov. 1, 1770. He was educated at Mareschal college, and intended for the church, but his conduct was marked by eccentricities which were the premonitory symptoms of that insanity with which he was afterward afflicted; and, abandoning his intention of becoming a minister, he went to London in 1724, where he supported himself by giving lessons in Latin and Greek. Afterward he obtained a position as tutor, and resided for some time in the Isle of Man. In 1732 he returned to London, where he was engaged as corrector of the press by a publishing house, with which occupation he combined that of bookseller, opening a small shop under the royal exchange. He had already commenced his "Concordance to the Holy Scriptures," which was completed and published in 1737, and dedicated to the queen, from whom he hoped for some substantial proof of royal munificence, a hope never realized; the queen died 16 days after the presentation of the work.

Cruden was three times in his life confined in a lunatic asylum: once soon after his departure from college, again immediately after the publication of his "Concordance," and a third time in 1753.
