Bader Philanthropies Inc.

Alfred Bader co-founded Aldrich Chemicals in 1951 out of a rented garage in Milwaukee. The firm later merged and is now part of Sigma-Aldrich Corp. A noted philanthropist, Alfred Bader has given tens of millions of dollars to his alma mater, Queen's University in Canada, and millions more to other causes. He is also an avid art collector. Isabel Bader has a keen interest in drama, music and early learning. Isabel and Alfred Bader decided the time was right to formalize their commitment to the foundation, which they have made contributions to since 2009. "We're all getting older, thank you very much," said Isabel Bader, who is 88. Alfred Bader, who had a minor stroke several years ago, is 90. Helen and Alfred Bader's sons, Daniel and David Bader, who serves as vice president, help oversee the foundation's work. They say their family is driven by the Jewish tradition of tzedakah, or charity.
