Geoengineer.org is extremely pleased to make available to what is, to date, a rare film featuring Karl & Ruth Terzaghi and colleagues. The original material was provided by Prof. Bengt H. Fellenius on October 2018 as a reel. It was professionally digitized and the raw footage, was made available online by Geoengineer.org. The video, which has no audio, features an outing involving Karl and Ruth Terzaghi, Arthur Casagrande, Friedrich (Fritz) Schaffernak, and Philipp Forchheimer along with family members.
