This does not seem like it should be controversial. Transhumanism is a direct outgrowth of Timothy Leary's 1970s "SMI^2LE" programme (Space Migration Increased Intelligence Life Extension), which in turn was directly influenced by L5 Society folks like Keith Henson and Gerald K. O'Neil. They, in turn, were directly influenced by Tsiolkovsky and other Cosmists. These influences were acknowledged by all parties involved.

Then it should be easy for you to show. I am fairly familiar with Henson and have read a number of his essays and emails from SL4 and Extropy days and I cannot recall a single instance showing that Tsiolkovsky had any particular influence asides from being, as I said, parallel developments. Eyes are a great idea, but that doesn't mean octopuses copied them from monkeys.
