David Deroy :"Bernard Heuvelmans était un scientifique qui avait aussi un côté poète"

• Hello,
  I read Heuvelmans books when I was a child and that is why I studied biology.
  Where could I find the documental in english, spanish or german if possible ?
  I can only find the short presentation of 1 minute.
  Thank you very much.
  Kind regards.
