In 1935, John's paternal grandparents died, leaving him about $1,900 ($42,224 today), then the equivalent of a year's salary for a middle-class man. John invested the money with the help of his brother, and in about 11 years, the value was such that he did not have to work. His investments, combined with a frugal lifestyle, resulted in a sum of over $500,000 at the time of his death.
