IEM 25th Anniversary
Posted: 22 Jun 2026 05:30 AM, Views: 248Tags: iem
The IEM project/website turns 25 years old this summer! Last week, a quasi-surprise celebration was organized by the ISU Agronomy Department (thank you Dr Brian Hornbuckle, Madelynn Wuestenberg, Rita Brueland, and others!) with many long term supporters of the IEM there to share stories and yummy food. The featured image presents yours truly attempting to hold the ice cream cake adorned with the IEM logo toward the camera without it spilling. Collaborators who helped develop the original project along with some of those who find funding support today are shown in the image. The Internet Archive captured how this website looked back on 19 July 2001. Here is to another 25 years
