When Dr. Nils K. Nelson, organic chemistry professor, retired from Purdue University Northwest (PNW) in 1991, he never considered leaving the place he loved. There were opportunities to relocate closer to family, but for Nelson, PNW’s Hammond Campus was home.Leaving an eternal mark at PNW may have been what Nelson, who taught 29 years at the university, had in mind when he planned a multimillion dollar gift from his estate—though he might not have expected his legacy would include a building in his name.The Purdue University Board of Trustees approved the official naming of the Nils K. Nelson Bioscience Innovation Building. Currently under construction on PNW’s Hammond Campus, the 68,000-square-foot building project officially broke ground in July 2018 and is set to open in fall 2020. The facility will contain research and teaching labs, and house PNW’s College of Nursing and the Department of Biological Sciences. It will be the first new academic building on the Hammond Campus in nearly 20 years.
