Emanuel Swedenborg

Emanuel Swedenborg (; Swedish: [ɛˈmɑ̂ːnʉɛl ˈsvêːdɛnˌbɔrj] ; born Emanuel Swedberg; 29 January 1688 – 29 March 1772) was a Swedish polymath; a scientist, engineer, astronomer, anatomist, Christian theologian, philosopher, and mystic. He became best known for his book on the afterlife, Heaven and Hell (1758). Swedenborg had a prolific career as an inventor and scientist. In 1741, at 53, he entered into a spiritual phase in which he began to experience dreams and visions, notably on Easter Weekend, on 6 April 1744. His experiences culminated in a "spiritual awakening" in which he received a revelation that Jesus Christ had appointed him to write The Heavenly Doctrine to reform Christianity.
