Has Nabokov commented explicitly on Alexander Herzen elsewhere apart from Speak, Memory? The nod to Herzen's From the Other Shore has been noted long ago as is this passage (as a caption to their Petersburg address):
"Aleksandr Ivanovich Hertzen (1812–1870) was a famous liberal (whom this commemoration by a police state would hardly have gratified) as well as the talented author of Bïloe i Dumï (translatable as “Bygones and Meditations”), one of my father’s favorite books."
