The Author

Thornton Wilder, the author of Our Town, was born in 1897 and comes from a well-educated family. His father was a US Consul General in Hong Kong and Shanghai. 'Wilder's mother was a cultured, educated woman who instilled a love of literature, drama, and languages in her children" (http://www.pbs.org/wgbh/masterpiece/americancollection/ourtown/ei_wilder.html).
Thornton studied Greek and Roman classics, then archeology, and French literature. He became a professor of French and taught poetry at Harvard.
While living in Chicago, Thornton got inspired by a work of his friend Gertrude Stein called The Making of Americans. Grover's Corners is a fictional town. However, it is based on a town called Peterborough in New Hampshire where Thornton used to spend his summers. He was a great philosopher and that is why he decided to write Our Town, a story of ordinary life together with (what I think) great philosophical ideas on life.
And one more interesting fact: Thornton Wilder is the author of The Matchmaker, a play that was transformed into musical Hello, Dolly!
