PMQ Pizza Magazine: Tom 'The Dough Doctor' Lehmann Passes Away from COVID-19:

Recalling Tom’s life and unparalleled contributions to the pizza industry, a famous quote by Sir Isaac Newton springs to mind: “If I have seen further, it is by standing on the shoulders of giants.” Tom was, like Newton, a scientist, with an almost encyclopedic knowledge of the chemistry and physics that underly the dough making and baking processes. And in our industry, he was a giant. It’s safe to say that countless pizzeria owners and pizza chefs have gotten far in this business by standing on Tom’s shoulders.

If there was ever a pizza version of "The Wolf" from Pulp Fiction, it was Tom Lehmann. For years Tom was super active and incredibly helpful on the PizzaMaking forums. He even has his own board called "Ask The Dough Doctor".

There's a ton of cargo culting and magical thinking in the online pizza making communities. Tom didn't have any of that. Whenever he brought answers to questions it was always backed by knowledge and experience and science, and most importantly kindness. The type of person Tom Lehmann was is rare, and he'll be missed.
