Two hundred years ago today, Henry David Thoreau was born in Concord. It was back in 1845 that he built a tiny cabin on the shore of Walden Pond in his hometown and penned a book by the same name that has inspired generations of readers.
Some credit it along with his other writings like "Cape Cod" with helping to launch the modern-day environmental movement.
Thoreau later penned many other works, including the book "Civil Disobedience," which has been cited as an inspiration by the likes of Mahatma Gandhi and Martin Luther King Jr.
Thoreau scholar Jeffrey S. Cramer spoke with WGBH's All Things Considered host Barbara Howard about Thoreau and his work.
