Alfred the Gorilla
Alfred died on 10 March 1948. The press at the time speculated that ‘his pet hate got him in the end’, linking Alfred's dislike of aeroplanes with the passage of one over the zoo shortly before his death. The actual cause of his demise was tuberculosis which he contracted a year before and despite his keepers best efforts, he had been unable to recover. His death was mourned by many of the regular visitors to the zoo, some of whom were even inspired to compose poems in his honour.
Alfred Adler
In the early 1930s, after most of Adler's Austrian clinics had been closed due to his Jewish heritage (despite his conversion to Christianity), Adler left Austria for a professorship at the Long Island College of Medicine in the US. Adler died from a heart attack in 1937 in Aberdeen, Scotland, during a lecture tour, although his remains went missing and were unaccounted for until 2007. His death was a temporary blow to the influence of his ideas, although a number of them were subsequently taken up by neo-Freudians. Through the work of Rudolf Dreikurs in the United States and many other adherents worldwide, Adlerian ideas and approaches remain strong and viable more than 70 years after Adler's death.
