Enhancing walls

Dave and I explaining the lac operon.

When we were teaching the summer courses at CSHL, Dave Featherstone (who, unfortunately, passed away in 2017) and I had admired the gigantic photographs of the famous biologists roaming the grounds of Cold Spring Harbor in the 50s and 60s. They were mounted high up in the lecture halls and corridors and we dreamt of once being put up there as well. However, it was not Dave’s style to wait for destiny to place us there. Instead, in the summer of 2009, we decided to re-take our favorite photos, printed them out as large as we could and put them up to the walls below the originals. They were hanging there for at least two years.

By the way, we also have to thank Dave for promoting the legend of the Gespenstermauer in Berlin:
