Robert Crumplebottom

Robert Crumplebottom was a renowned philanthropist and puppeteer. He was first mentioned in The Sims: Hot Date.

History
Robert Crumplebottom was first mentioned in The Sims Hot Date as a description for "Crumplebottom Park", a park made in memory of him. He then was mentioned again in The Sims Vacation in the description of the Crumplebottom chandelier, which goes like this:

"This lamp is a remarkable recreation of a stage prop for the late, great Robert Crumplebottom. The original chandelier became famous when, during his annual winter charity performance, the lamp dropped a full two stories, landing upon the esteemed puppeteer and ending his short, but inspiring life. This replica is a testament to both his brilliance and his unfortunate end."

Both Robert Crumplebottom and Mrs. Crumplebottom (a.k.a. Agnes Crumplebottom) had first appeared in The Sims Hot Date, and it is rumored that his death was the cause of her constant crabbiness.

The Sims 2
It is revealed in The Sims 2 that Cornelia Goth's maiden name was "Crumplebottom", so it is clear that Robert Crumplebottom was somehow linked to the family. Other than this, Robert is not mentioned in The Sims 2.

The Sims 3
In The Sims 3, Robert's death makes Agnes an unhappy widow. By being married

Though he is dead, he and his wife still have a relationship, as suggested by the pictures below. If you resurrect him (which is rumored to be possible by taking his urn to the science lab), Agnes will automatically become pregnant with twins as an Easter Egg.

It was somehow believed that a ghost named Erik Darling was Agnes' husband, but this is evidently not true. If you closely compare the picture of the ghost of Erik Darling and the pictures of the ghost Agnes is hugging in the cemetery, you can see that they are not the same ghost.
