Later in his life, Buttenwieser became involved in politics and was, as described by Mother Jones magazine in 2004, among the most generous Democratic donors for nearly a decade. In 1997, he was the fourth largest "soft money" donor to the Democratic Party, and was the sixth largest donor in 1999. He was also among the largest political contributors in Pennsylvania and supported for the campaigns of prominent politicians such as Ed Rendell, Paul Wellstone, Michelle Nunn, Tammy Baldwin, and Bob Casey Jr. During the 2000 United States presidential election alone, he donated $1 million to various Democratic Party candidates.

In 1986, Buttenwieser remarried Terry Ann Marek, who had a daughter before the marriage.

Buttenwieser taught at the Dalton School for two years before leaving for Uganda as part of a federal teaching exchange program. During the mid-1960s, he taught in Winston-Salem, North Carolina, headed the Pennsylvania Advancement School, and founded the Durham Child Development Center in 1970.

In 1960, Buttenwieser married Radcliffe College graduate Elizabeth Werthan, daughter of Albert Werthan, chairman of Nashville-based Werthan Industries. They had two daughters, Sarah Buttenwieser and Julie Suh, before divorcing.

He attended the Putney School in Vermont and graduated from Columbia College in 1958. He then received his master's degree in history from Harvard University before earning a doctorate from Teachers College, Columbia University.
