Fast Facts
Born in Miami in 1955 to two professor parents, Browner grew up hiking in Florida's Everglades and credits that experience with helping her develop a close connection to the natural world.
Received a B.A. in English and a law degree from the University of Florida in Gainesville.
She is married to Thomas Downey, a former Democratic congressman from New York; she has one son from a previous marriage. Downey is chairman of a lobbying firm with dozens of clients, which until Dec. 12 included several with interests in energy policy, according to the company COO.
She was named "Mother of the Year" in April 1997 by the National Mother's Day Committee for her dedication to providing "children with a safer, healthier world." She was also named Glamour magazine's Woman of the Year in 1998.
Out of college, Browner became an aide in the Florida house of representatives, but left for Washington D.C. a few years later to work for Citizen Action, a grassroots organization that lobbies for a variety of issues, including the environment.
From 1989 to 1991 she served as Senator Al Gore's senior legislative aide before heading up the Department of Environmental Regulation in Florida. Her greatest achievement: settling a lawsuit the government had brought against Florida for environmental damage done to Everglades National Park and launching the largest ecological restoration project ever attempted in the U.S., to purify and restore the natural flow of water to the Everglades.
After being appointed EPA administrator in 1993, she put forward a plan to improve the agency's decision making, conserve money and "restore [its] credibility."
In 1996 Browner led a campaign to have Congress reauthorize the Safe Drinking Water Act and spearheaded the Food Quality Protection Act, which modernized standards that govern pesticide use, one of the first environmental laws to specifically protect children's health.
Currently is a principal of former Secretary of State Madeleine Albright's global strategy firm, the Albright Group, working in the areas of environmental protection, climate change and energy conservation and security.
Quotes by Browner:
On EPA critics in the business community: "I've found business leaders don't oppose strong environmental programs. What drives them crazy is a lack of certainty. We can change that." (New York Times, Dec. 17, 1992)
On her goals as EPA administrator: "I want my son to be able to grow up and enjoy the natural wonders of the United States in the same way that I have." (At her swearing-in ceremony, January 1993)
On her years working with President Clinton, Vice President Gore and a Republican Congress: "I think one of the most difficult moments for the agency was when the Republican leadership in Congress literally shut us down, wouldn't give us our funding, tried to limit our ability to enforce the law, you know, not once, not twice, but I think 17 times. Those were some difficult days, not just for EPA, but I think for the entire country. And thankfully, we had a Vice President who said no, who was prepared to veto bills." (NPR, Dec. 22, 2000)
