It was used for a brief time by the statistics department of the university. Atanasoff & Berry were called off to war work elsewhere and abandoned the machine. The university needed more classroom space during the war and finding ABC too large to fit through the door (by an inch or two) cut the machine up and scrapped most of it.

He is most known now for the Atanasoff-Berry Computer, but I'm sure he invented many other things.

1937, in an Indiana bar by Dr. John Vincent Atanasoff. He and Clifford Berry finished building it in early 1942 but after they left Iowa State University to perform war related work, the machine was soon scrapped when the room it was in needed to be converted to classrooms and the machine was found to be too wide to roll it out through the door.

Dr. John V. Atanasoff and his assistant Clifford Berry built the first electronic digital computer. It was called the Atanasoff-Berry-Computer (ABC)
John Vincent Atanasoff was 34 years old when he invented the ABC in an Illinois bar in the winter of 1937-38. Clifford Edward Berry did not become involved until 1939, he was a graduate student "hired" by Atanasoff to help with final circuit design and assembly.

The ABC (Atanasoff-Berry Computer) was a non-programmable, digital calculation machine invented by Dr John Atanasoff and his grad student Chris Berry in 1942.
Became operational in 1942
