Here are some events that happened on October 20th. It could be an event or a person that died or was born on that day

1859 Born: John Dewey, American psychologist and philosopher (d. 1952)

John Dewey (October 20, 1859 – June 1, 1952) was an American philosopher, psychologist, and educational reformer whose ideas have been influential in education and social reform. He is regarded as one of the most prominent American scholars in the first half of the twentieth century.

The overriding theme of Dewey's works was his profound belief in democracy, be it in politics, education, or communication and journalism. As Dewey himself stated in 1888, while still at the University of Michigan, "Democracy and the one, ultimate, ethical ideal of humanity are to my mind synonymous." Known for his advocacy of democracy, Dewey considered two fundamental elements—schools and civil society—to be major topics needing attention and reconstruction to encourage experimental intelligence and plurality. Dewey asserted that complete democracy was to be obtained not just by extending voting rights but also by ensuring that there exists a fully formed public opinion, accomplished by communication among citizens, experts, and politicians, with the latter being accountable for the policies they adopt.

Dewey was one of the primary figures associated with the philosophy of pragmatism and is considered one of the fathers of functional psychology. His paper "The Reflex Arc Concept in Psychology," published in 1896, is regarded as the first major work in the (Chicago) functionalist school. A Review of General Psychology survey, published in 2002, ranked Dewey as the 93rd-most-cited psychologist of the 20th century.

Dewey was also a major educational reformer for the 20th century. A well-known public intellectual, he was a major voice of progressive education and liberalism.  While a professor at the University of Chicago, he founded the University of Chicago Laboratory Schools, where he was able to apply and test his progressive ideas on pedagogical method. Although Dewey is known best for his publications about education, he also wrote about many other topics, including epistemology, metaphysics, aesthetics, art, logic, social theory, and ethics.

1964 Died: Herbert Hoover, American engineer and politician, 31st President of the United States (b. 1874)

Herbert Clark Hoover (August 10, 1874 – October 20, 1964) was an American engineer, businessman, and politician who served as the 31st president of the United States from 1929 to 1933. A member of the Republican Party, he held office during the onset of the Great Depression. Before serving as president, Hoover led the Commission for Relief in Belgium, served as the director of the U.S. Food Administration, and served as the 3rd U.S. Secretary of Commerce.

Hoover was born to a Quaker family in West Branch, Iowa. He took a position with a London-based mining company after graduating from Stanford University in 1895. After the outbreak of World War I, he became the head of the Commission for Relief in Belgium, an international relief organization that provided food to occupied Belgium. When the U.S. entered the war, President Woodrow Wilson appointed Hoover to lead the Food Administration, and Hoover became known as the country's "food czar". After the war, Hoover led the American Relief Administration, which provided food to the inhabitants of Central Europe and Eastern Europe. Hoover's war-time service made him a favorite of many progressives, and he unsuccessfully sought the Republican nomination in the 1920 presidential election.

After the 1920 election, newly elected Republican President Warren G. Harding appointed Hoover as Secretary of Commerce; Hoover continued to serve under President Calvin Coolidge after Harding died in 1923. Hoover was an unusually active and visible cabinet member, becoming known as "Secretary of Commerce and Under-Secretary of all other departments". He was influential in the development of radio and air travel and led the federal response to the Great Mississippi Flood of 1927. Hoover won the Republican nomination in the 1928 presidential election, and decisively defeated the Democratic candidate, Al Smith. The stock market crashed shortly after Hoover took office, and the Great Depression became the central issue of his presidency. Hoover pursued a variety of policies in an attempt to lift the economy, but opposed directly involving the federal government in relief efforts.

In the midst of the economic crisis, Hoover was decisively defeated by Democratic nominee Franklin D. Roosevelt in the 1932 presidential election. After leaving office, Hoover enjoyed one of the longest retirements of any former president, and he authored numerous works in subsequent decades. Hoover became increasingly conservative in this time, and he strongly criticized Roosevelt's foreign policy and New Deal domestic agenda. In the 1940s and 1950s, Hoover's public reputation was slightly rehabilitated after serving in various assignments for Presidents Harry S. Truman and Dwight D. Eisenhower, including as chairman of the Hoover Commission. Though he managed somewhat to rehabilitate his legacy, Hoover is still widely regarded as an inadequate U.S. president, and most polls of historians and political scientists rank him in the bottom third overall.

1973 – The Sydney Opera House is opened by Elizabeth II after 14 years of construction.

The Sydney Opera House is a multi-venue performing arts centre at Sydney Harbour in Sydney, New South Wales, Australia. It is one of the 20th century's most famous and distinctive buildings.

Designed by Danish architect Jørn Utzon, but completed by an Australian architectural team headed up by Peter Hall, the building was formally opened on 20 October 1973 after a gestation beginning with Utzon's 1957 selection as winner of an international design competition. The Government of New South Wales, led by the premier, Joseph Cahill, authorised work to begin in 1958 with Utzon directing construction. The government's decision to build Utzon's design is often overshadowed by circumstances that followed, including cost and scheduling overruns as well as the architect's ultimate resignation.

The building and its surrounds occupy the whole of Bennelong Point on Sydney Harbour, between Sydney Cove and Farm Cove, adjacent to the Sydney central business district and the Royal Botanic Gardens, and close by the Sydney Harbour Bridge.

The building comprises multiple performance venues, which together host well over 1,500 performances annually, attended by more than 1.2 million people. Performances are presented by numerous performing artists, including three resident companies: Opera Australia, the Sydney Theatre Company and the Sydney Symphony Orchestra. As one of the most popular visitor attractions in Australia, the site is visited by more than eight million people annually, and approximately 350,000 visitors take a guided tour of the building each year. The building is managed by the Sydney Opera House Trust, an agency of the New South Wales State Government.

On 28 June 2007, the Sydney Opera House became a UNESCO World Heritage Site, having been listed on the (now defunct) Register of the National Estate since 1980, the National Trust of Australia register since 1983, the City of Sydney Heritage Inventory since 2000, the New South Wales State Heritage Register since 2003, and the Australian National Heritage List since 2005. Furthermore, the Opera House was a finalist in the New7Wonders of the World campaign list.
