Today’s Google Doodle honors Alice Paul, the American suffragist who played an integral role in getting the 19th Amendment passed, giving women the right to vote, and was the original force behind the Equal Rights Amendment.

Joining the National American Woman Suffrage Association (NAWSA) in 1912, Paul dedicated her life to women’s rights. She led the Washington, DC chapter of the organization and was the first to organize groups that picketed the White House.

During Woodrow Wilson’s term, Paul founded the National Women’s Party. She and her “Silent Sentinels” demonstrated in front of the White House, marching day and night while holding banners asking questions like, “Mr. President, how long must women wait for liberty?”

“Mr. President, how long must women wait for liberty?” — Alice Paul

In 1975, after a decades long search that involved thousands of volunteers and spanned an entire continent, Ken Brugger and Catalina Trail unlocked one of nature’s most beautiful mysteries: the overwintering place of the monarch butterfly. Led by a team of Canadian Zoologists under Fred Urquhart, the couple followed clues left by tagged butterflies that had strayed or fallen on their migratory journeys south. The scene, in which millions of monarchs cling to oyamel trees in Mexico’s easternmost Sierra Madre Mountains, would have been overwhelming. “They swirled through the air like autumn leaves,” said Urquhart after his first visit, “carpet[ing] the ground in their flaming myriads on the Mexican mountainside.”

With today’s homepage, Artist Kevin Laughlin recognizes the 41st anniversary of an incredible discovery and the singularly awesome beauty of the monarch butterfly.
