The last of Glasgow's great eccentrics was a Yorkshireman, Albert Ernest Pickard Unlimited, as he liked to call himself. Born in Bradford in 1874, he moved to Glasgow in 1904, buying Fell's Waxworks in the Trongate. He added his own American museum. introducing many weird freak shows to the stage and even had a small zoo on the premises.
it could be argued that the Panopticon's best years started in 1906, when the Yorkshireman A E Pickard became the proprietor. Mr Pickard was a well liked character in Glasgow, a showman through and through. With his guidance, the Panopticon became a music hall, an amusement arcade, a zoo, waxwork museum, and a freak show.
