Today is the 100th anniversary of the birth of Rachel Carson, well known for writing Silent Spring, the book that reversed a policy of widely spraying pesticides and is sometimes considered the launching point of the environmental movement.
Last winter I mentioned re-reading it in the original New Yorker verison. The accompanying photo, from about 1940, shows Ms. Carson as an employee of the US Fish & Wildlife Service; see the National Conservation Training Center history page. The Washington (DC, US) Post has a nice series of photos of Ms. Carson.
We live in a better world than it would have been had Ms. Carson not spoken so powerfully.
