One begins to see why there were whole rooms of people (women if you prefer accuracy over non-sexism) with pencils, paper and enough math and physics to perform basic ray-tracing. Walter Mandler designed that lens with their help, and couldn't have done it without them. It's true that computers do it better, but they do it better than the human eye, so we come to love older images as they mimic the effect of the Mark I eyeball (if you prefer the eyeball over accuracy!)
Where they worked in Wetzlar:
There are many examples of such lenses out there for those who appreciate them. Look especially for the pre-ASPH 35mm Summilux, the Summilux 75mm and the Noctilux 50mm f1.0.
