We had an interesting discussion at today’s Journal Club talk regarding people’s ‘grandfathers’, by which is meant their supervisor’s supervisor(‘s supervisor(‘s supervisor(‘s supervisor(you get the idea)))). It turns out the Stephane’s great-great grandfather was Alexander Fridman of cosmological fame, and he supervised George Gamow, who supervised Vera Rubin, who supervised Sandra Faber, who supervised Stephane Courteau. That’s quite the lineage. Meanwhile, Kayll Lake’s great-grandfather was none other than Eddington (and he seems to have been a rather poor supervisor). Rob’s is Martin Rees. James, my office mate, has John Landstreet from Western as a grandfather, and it turns out that my grandfather is Michael Turner of Chicago. I don’t know anything about him, but I was just curious.
