What is "evanion"

Henry Evans (c. 1832 – 17 June 1905) was a conjurer, ventriloquist and humorist, born in Kennington, South London, who used the stage name Evanion. Performances in front of members of the British Royal Family, including Queen Victoria at Sandringham, and the Prince of Wales (later Edward VII) and Princess Alexandra at Marlborough House, enabled him to use the name "The Royal Conjuror" in his publicity.
