Friedrich Schmiedl (1902 – 1994) was an Austrian rocket designer; known particularly for his development of rocket mail.
When the Second World War began, there was military interest in his work; however Schmiedl, not wishing his research to be used for military purposes, destroyed the research documents. After the war he declined an offer to work on rocket development in the USA.
