Did your grandmother and/or grandfather pass away before you were born? Why?

My maternal grandmother died in a house fire before I was born. She burned to death.
And my paternal grandfather passed away while doing a job in another country. He was in a truck with two other men going home after work and my grandfather was sitting in the middle seat of the truck when it struck a tree and killed him.
