Professor Hoffmann is the pen name of Angelo John Lewis (1839-1919), an English barrister and prolific writer, best known for his seminal work on magic and recreational pastimes. 'Modern Magic: A Practical Treatise on the Art of Conjuring' stands as a cornerstone of magical literature, first published in 1876. It presented a comprehensive guide to performing magic tricks and illusions, covering various aspects from card magic to stage illusions, and it became a foundational text for both amateur and professional magicians alike. Hoffmann's systematic and didactic approach demystified the art of magic by providing clear explanations, diagrams, and an understanding of the principles behind illusions. His literary style is characterized by precision, clarity, and thoroughness, reflecting his intent to make the art of magic accessible to a broader audience. Furthering his contributions to the field, Professor Hoffmann authored a series of books on games, puzzles, and magic, solidifying his reputation as an authority on recreational subjects. His impact on the world of magic is still recognized today by performers and enthusiasts who continue to study his works as essential reading in their craft.
