"Until now no concern had been expressed about the possible side-effects of the rejuvenation operations. But on 12 May 1921, the death in London was announced of Alfred Wilson, a wealthy septuagenarian, who had made his money in ship-breaking. This otherwise unremarkable event had aroused interest because some months previously he had gone to Vienna and had undergone the Steinach operation. On his return to London he had felt so well that he booked the Albert Hall in London to deliver a lecture entitled 'How I Was Made Twenty Years Younger'. A little while before the lecture he had visited his doctor and complained of some chest pain. Both doctor and patient agreed that this discomfort was the result of Wilson's new habit of hitting himself on the chest to demonstrate his renewed virility. However, the pain probably came from a coronary artery disease and Wilson dropped dead from a heart attack twelve hours before giving his lecture. At the inquest into the the death it was mentioned that Dr Steinach had charged £700 for the operation."
