Frank Jr Polk (born 1911)

In 1911, in the year that Frank Jr Polk was born, the first Indianapolis 500 was run in May. Ray Harroun was the winner - he was an engineer and had retired from racing but he came back for this race. After the race, he retired for good. The purse was $27,550 - the largest offered up to that time - and Harroun received $10,000 for first place. His average time was 74.602 mph.

In 1926, on October 31st, Harry Houdini died in Michigan. Houdini was the most famed magician of his time and perhaps of all time, especially for his acts involving escapes - from handcuffs, straitjackets, chains, ropes slung from skyscrapers, and more. He was president of the Society of American Magicians and stringently upheld professional ethics. He died of complications from a ruptured appendix. Although he had received a blow to the area a couple of days previously, the connection between the blow and his appendicitis is disputed.

In 1934, on June 6th, the U.S. Securities and Exchange Commission was formed as a response to the stock market crash of 1929 and the continuing Great Depression. Previously, the states regulated the offering and sales of stocks - called "blue sky" laws. They were largely ineffective. Roosevelt created a group (one member was Joseph Kennedy, father of the future President Kennedy) who knew Wall Street well and they defined the mission and operating mode for the SEC. The new organization had broad and stringent rules and oversight and restored public confidence in the stock market in the United States.

In 1947, on April 15th, Jackie Robinson joined the Brooklyn Dodgers, playing first base. He was the first black man to play in the Major Leagues. Since the 1880's, professional baseball had been segregated and blacks played in the "Negro leagues". He went on to play for 10 years.

In 1974, on July 30th, the House Judiciary Committee adopted three articles of impeachment against President Nixon. He was charged with obstruction of justice, failure to uphold laws, and the refusal to produce material subpoenaed by the committee. In order to avoid impeachment, Richard M. Nixon announced that he would resign on August 8th, the first President to do so.
