Ames’ most influential organization during World War II celebrated its 50th anniversary last month.

The Ames Laboratory, known for its contributions to the making of the atomic bomb, held a reception May 16 in honor of its 50 years dedicated to research.

The reception was held in front of the new Technical and Administrative Service Facility, which is located behind Spedding Hall. Laboratory employees, representatives of Iowa State and city and government officials attended the commemoration.

“There was a great turnout for the event, which made for a great party,” said Steve Karsjen, public affairs manager for Ames Lab.

A highlight of the celebration was the unveiling of a historical display. The exhibit depicts the contributions lab scientists made to the Manhattan Project, which resulted in the formation of the Ames Lab.

Karsjen said all are welcome to visit the display, which is located on the first floor of the Technical and Administrative Service Facility.

The Ames Lab was established by the United States Atomic Energy Commission in May 1947 on the Iowa State campus. Its purpose was to build and maintain a strong group of scientists working in the fundamental sciences.

Under Frank H. Spedding, the lab’s first director, scientists helped produce the uranium used in the atomic bombs that fell on Japan.

Since it opened, many important developments have resulted from the research completed at the Ames Lab. Today it is one of the world’s foremost materials research centers, Karsjen said.

The Ames Lab is operated for the Department of Energy by ISU. Karsjen said it conducts research into various areas of national concern including energy resources, high-performance computing and environmental cleanup and restoration.
