Pairs - I see pairs
Friedrich Engels / Steve Jobs
Gustav Mahler / Lou Reed
Funny how it's easier to pin a year on a 1907 portrait than a 2000 one.
Mahler's wife, Alma Schindler, was also a composer, which seems to have caused some friction. She was associated romantically with Gustav Klimt and after Mahler's death, she was also married to the architect Walter Gropius, and poet Franz Werfel.
Lou Reed's wife, Laurie Anderson, is also a performer and artist. It seems to have caused not friction, but mutual inspiration.
It is just almost remotely possible for Lou Reed to have been the "love grandchild" of Gustav Mahler. Reed's father, Sidney Joseph Reed was born Sidney Joseph Rabinowitz in New York City in about 1913. Mahler was in New York from 1907 to 1911, returning to Vienna in 1911 where he died a month later. He learned of his wife's affair with Gropius in 1910. If Reed's father's birth date is wrong (and it seem to be uncertain) ... well who's to say? Note, I'm being silly here, ok?
Dimitri Shostakovich / Harry Potter
Continuing with the composer theme ... Look at young Dmitri Shostakovich!
Bessie Smith / Janis Joplin
I think there might have been something intentional about this ...
