Heidelberg Stadthalle
Information:
The 28th World Science Fiction Convention, also known as Heicon '70, was held 20-24 August 1970 at the Heidelberg Stadthalle in Heidelberg, West Germany.
Manfred Kage eventually became Heicon's convention chairman, the last of more than a dozen fans who briefly held the position during the convention's rocky organizational period. The professional guests of honor were E. C. Tubb (UK), Robert Silverberg (US), and Herbert W. Franke (Germany). Elliot K. Shorter, the 1970 Trans Atlantic Fan Fund (TAFF) winner, was the fan guest of honor. The toastmaster was John Brunner.
