[1] The son of Richard Caleb Morrison, Morrison joined the Royal Navy in 1806 serving as a first-class volunteer until 1810, as a master's mate until 1815, and resigned due to ill-health with the rank of lieutenant in 1829.
[2] In 1831, Morrison issued The Herald of Astrology, which was subsequently known as Zadkiel's Almanac.
In this annual pamphlet, he published predictions of the chief events of the coming year.
In 1863, he won a libel suite against Admiral Sir Edward Belcher, who wrote in the Daily Telegraph that Morrison was "the crystal globe seer who gulled many of our nobility about the year 1852".
[3] The Athenaeum (16 May 1874, p. 666) noted that Morrison was “the restorer and Grand Master in this country of Tao-Sze, a secret society intended to be of immense power, and to outshine the Free- masons, but which, most probably, by his death, is reduced to two members, and inanition”.
