Grinnell College announced that it has received a $1 million pledge from an alumni couple that will support the college’s new humanities and social studies complex. The pledge by Karen Van Dusen and Joel Spiegel, a Grinnell College trustee, is the largest to date for a long-term campaign to improve the college’s academic spaces. The college expects to launch a public campaign next year to raise $20 million for the project, which includes a major renovation of Alumni Recitation Hall and Carnegie Hall. The couple previously committed $250,000 for curriculum-embedded global learning opportunities. In a similar fashion, their new gift demonstrates their commitment to providing students with “connected and relevant” experiences, Grinnell officials said in a release.
