@freemo I don't know. But this is where he worked for most of his life, where his experiments to create the model were executed, and where first dives using his tables happened (Lake Zürich is more than 100m deep in the deepest point).
@robryk I might need to come out there for a dive then!
@freemo Then you might find https://www.swiss-divers.ch/informationen/tauchplaetze/zuerichsee-tauchplaetze/ useful. Disclaimer: I have no clue how accurate that is.
@robryk I cant read it anyhow without a translator. So I cant speak to its accuracy either.
@robryk is that where the guy was born?
