Sir Nicholas Winton was a British philanthropist who rescued 669 children, mostly Jewish, from German-occupied Czechoslovakia just before World War II. Winton's work is known as the "Czech Kindertransport".

Winton was born on May 19, 1909 in West Hampstead, London. His father was a bank manager. Winton was educated at Eton College and then studied economics at the City of London School of Economics.

In 1938, while on a business trip to Prague, Winton met a group of Czech volunteers to help Jews escape Nazi persecution. Together with these volunteers, Winton tried to find a safe country for children. Winton chose England as a safe country for the children.

The British government had started a program for children to come to England. Winton found sponsors for the children to take advantage of this program.

Winton started a campaign in England and Czechoslovakia to find sponsors for children to come to England. In this campaign, Winton received support from wealthy businessmen, church leaders and other philanthropists.

After finding sponsors, Winton prepared the necessary documents to send the children to England. In preparing these documents, Winton recorded the children's names, ages and information about their families.

Between 1938 and 1939, Winton worked to send 669 children to England. Winton sent these children first by train to Vienna and then by ship to England.

Winton's work saved the lives of thousands of children who survived Nazi genocide during World War II. Winton's work is known as the "Czech Kindertransport".

Winton's work ended in 1939, when the Nazis invaded Czechoslovakia. Winton returned to England after this invasion.

Winton's work was forgotten after the war. Winton received no awards or recognition for his work. Winton commented on this by saying, "People should not expect to be rewarded for their good deeds."

Winton's work was uncovered in 1988 by a British journalist, Trevor McDonald. After McDonald uncovered Winton's work, Winton became known around the world.

In 2003, Winton was knighted by Queen Elizabeth II. Winton received this title for his work on "Czech Kindertransport".

Winton died at his home in Oxfordshire on July 1, 2015, at the age of 106. After Winton's death, people all over the world praised his work.

Winton's work has an important place in history, as it saved the lives of thousands of children who survived Nazi genocide during World War II. Winton's work is an example of humanity's conscience and benevolence.
