not sure i could manage 5 but here goes...
paul daniels: yep corny but i grew up watching his show and he was entertaininng had great variety and was great inspiration to start and showed the power and beauty of a skill (i bet everyone still loves his cup routine

my dad: encouraged me, took me to shops, gave me some of his books (encyclopaedia of card magic still one of my favourites - thats where it started) from magic books by post or somewhere (is this still in business?) his svengali deck, and great advice

probably the best reason i ever got into this art in the first place!
jean hugard: reading the 'card manipulations' books and others, seeing the skills he built up and that no matter how good you got (or thought you did) someone else was better and could do something you couldnt and there would always be some new take on a sleight, got me to keep practicing and striving to improve my skills and knowledge.
just about every well known magician the 19th and early 20th centuries: forgive me im a bit of a history nerd and a romantic. but something about the period, the audiences and the work ethic used in the craft has me day dreaming. a time when magic wasnt just a show of the 'supernatural' but made it the art form and entertainment we love today. innovation, study, an urge to do greater things, participation, fun and change with the environment around them are really the principles we all aspire to today to keep it entertaining, fresh, and continuing. really its because of them we all can do what we do.
