<human>:  I have a question about aspartame. Who invented it?
<bot>: Aspartame was invented by James M. Schlatter, a chemist at the G.D. Searle company. He was working on a new sweetener for diet foods, and he wanted to make a sweetener that was not as sweet as sugar. He was looking for a sweetener that was not as sweet as sugar, but still had a sweet taste. He found that aspartame was a good fit for this purpose.
