Later Life
Cantor suffered from his second bout of depression in 1889 and then the death of his son worsened his condition so much so that he lost all of his enthusiasm for mathematics and life in general. Meanwhile attempts to prove the many problems in his Set Theory were continually being made by various mathematicians. Cantor felt utterly humiliated when his theory was criticized in the third International Congress of Mathematicians. He suffered from serious depression after this incident. He also faced condemnation from many Christian Theologians and mathematicians on his philosophy on the relationship between the Absolute Infinite and God and his belief that he had been chosen by God himself to reveal his mathematical views to the world.
His achievements are widely recognized Today. He was made an honorary member of London and Kharkov Mathematical Societies in 1901. He also received honorary degrees from many universities. He was one of the most distinguished mathematicians who unfortunately lived his last days in poverty and illness. He even suffered from lack of food during the First World War. In 1917 he lived in his last sanatorium (the psychiatric hospital in Halle) and died the following year on 6th of January 1918.
