1699-1770. Scottish author of the famous Concordance which is still the standard reference guide to the [[King James Version]]. Shortly after graduating from Aberdeen he suffered a mental breakdown and was confined to an asylum (1721-22). Upon his release he went to London, where at first he was a tutor, but later opened a bookstore and did proofreading. The first edition of his concordance appeared in 1737. It was not a financial success, and the pressure of the work caused him to suffer another attack of insanity (1738). Confined again, he escaped after a few weeks and issued an indignant account of his experience entitled The London Citizen Exceedingly Injured, or a British Inquisition Displayed. He then sued for damages, but lost the case. Confined a third time in 1753, he was released by the following year and once more set to work on his concordance.
