Fonda Sera, owner of Zuzu’s Petals on Fifth Avenue responded to my post about Ed Rogowsky. There’s more about the street sign and the man on Here is Park Slope:

this is a bit of what i know about him.

i met him and his partner, Peter, and their dog betty,a million years ago
in the flowershop on seventh avenue.

ed was very funny and always sweet to me

he was one of those gung-ho brooklyn movers and shakers that there used to
be so many of back then. he was, i think on the city planning board and i know
he was a neighbor and mentor of Craig Hammerman of CB6.

he had his own  show on cuny tv.

he was president of my co-op on sterling place and was a great help when i
was buying my apartment.

he died too soon and suddenly, it was a terrible to shock to everyone who
knew him.

it was a great day when sterling place was named ed rogowsky way….
