2021 Lifetime Membership


Nebraska Innovation Campus Hand Sanitizer Team

Hunter Floodman, David Martin, Jerry Reif, Max Wheeler, Terry Howell Jr.

In the early summer of 2020, as the first of wave of the pandemic was surging, a planning team at the University of Nebraska-Lincoln estimated that, when the campus fully reopened in fall 2020, more than 100 gallons of hand sanitizer would be needed per day.

A team identified 1,000 locations that would benefit from a hand sanitizer dispensing station, including student housing, Campus Recreation, Nebraska Unions, athletics, 83 Nebraska Extension offices and one wall dispenser in every elevator on campus. Under the leadership of Jim Jackson, associate vice chancellor of university operations, a team was formed to solve the problem of efficiently distributing hand sanitizer across campus. They invented a large-capacity, free-standing hand sanitizer dispenser station that was in large part produced at Nebraska Innovation Campus.

The team of David Martin, Jerry Reif, Max Wheeler, Terry Howell Jr. and Hunter Floodman sprung into action. Through their efforts, persistence and innovation, the need for hand sanitizer was not only met, but exceeded. Hand sanitizer was made available to the College of Dentistry for use when supply was short and in high demand.
