The Stock Market Crash of 1929, also known as the Wall Street Crash of 1929, and The Great Crash, ran from Black Thursday (October 24) to Black Tuesday (October 29) in 1929. It was the most devastating stock market crash in the history of the United States. It was one of the factors that led to the Great Depression.
The crash led to a great period of poverty, which led some people to attempt to commit suicide. At some point in 1929, the ladder on the Hill Valley Courthouse was removed after a number of jumping incidents.
After the crash, Sarah Brown developed a distrust of banks — and even safes — and began keeping her money in her house. Some time after her husband died, she began seeing a new suitor. Her son, Dr. Emmett Brown, feared that he might be solely dating her for her money. Thus, he took her money and buried it in the woods, leaving a map to the money on the back of a painting of his mother commissioned by his father.
Some time later, Doc realized that he needn't be worried once he discovered that his mother's suitor was J. Carlton Ellsworth, from the wealthiest family on the western coast of the United States. Doc needed money to finance his time machine experiments, so he dug up the money himself, without telling his mother.
