Peter Dinsmore was a scientist for LuthorCorp.
The death of their daughter took a toll on Pete Dinsmore's marriage to his wife and they ended up getting divorced. Not being able to move on, he began experimenting with cloning, as a means to restore Emily back to life. During this time, he also began working for LuthorCorp. However, the cloning project was put at risk, when his most successful experiment escaped and went after Emily's childhood friend, Lana Lang.
When the clone was recaptured by LuthorCorp, Pete was removed from the project as a punishment. He was killed by the Emily clone, a year later, when she again broke out and went after Lana.
