Err, might be to soon but...
...why don't we just clone him?
Biologist Keith Campbell, famous for creating the first cloned mammal, Dolly the sheep, has died aged 58, the University of Nottingham said. Professor Campbell's creation of a live Ovis aries clone in 1996 was an incredible event, thrilling scientists with a breakthrough that paved the way for other successful cloning …
Because only 1 in 277 attempts of the technique he championed was successful and he said himself that it would never be viable for human cloning.
I'm not anti-clone (which is a bit like being anti-science in a way), but it's not a terrible useful or reliable technique even years after Dolly.
Humour brought down to stark reality, so the reason they didn't clone him is that the sheep that inherited his estate said it wasn't viable science.
I thought it was that the clone started out at the same age as the original was at the time the cells were taken. Cloning a dead scientist (or otherwise) would just create an old young man.
In any event, I wouldn't clone myself because of that Calvin & Hobbes episode with the Duplicator...
