The school said the campaign will focus on building Northwestern as a global leader in innovation, research and creative expression. The campaign gifts will go toward renovating facilities on both the Evanston and Chicago campus, as well as endowed professorships, student scholarships, laboratories and research, and other areas to "solidify Northwestern's position among the world's leading research universities," according to a statement.
The university has raised $1.52 billion toward the campaign already.
Northwestern University President Morton Schapiro said he hopes to also raise the number of donors participating in the campaign.
The school asked alumni to wear purple on Friday to celebrate.
