As a representative, Richardson was a strong proponent of free trade in North America, Native American sovereignty and environmental concerns. He also distinguished himself as the three-time Most Valuable Player in the annual Congressional baseball game pitting Democrats against Republicans.

Richardson has served as special envoy to President Clinton on sensitive diplomatic missions. He has rescued Americans held hostage in Iraq, Cuba, Sudan and North Korea. He helped negotiate the restoration of President Jean-Bertrand Aristide in Haiti.

In the course of his service, Richardson has been nominated for the Nobel Peace Prize three times and has been given the Aztec Eagle Award from the Mexican government, the highest honor Mexico bestows on a foreigner.

"He's not only an accomplished politician, but is also someone who understands and has succeeded in affecting and improving public policy," Nagurka said. "He's always been a doer. I have no doubt that it will be not only an enjoyable experience from a student's perspective, but also most educational."

Richardson said he is looking forward to his Harvard stay.

"There have been some extraordinary people associated with the Kennedy School over the years, and I am honored to be part of a cadre of former government officials who share our unique experiences with tomorrow's leaders," said Richardson in a KGS press release Wednesday.

Returning to private citizenship, Richardson plans to open a conflict resolution center and to teach in his home state of New Mexico as well. He is considering writing a book about his experiences in international hostage rescue as a member of Congress. Richardson also intends to give speeches around the country and to sit on a number of boards.
