The Flags At Geno's Are At Half-Mast

The man most responsible for delicious Philly cheesesteaks has passed away.

MADISON, Wis. - Edwin Traisman, a food scientist who created the process for freezing McDonald's french fries and helped develop Cheez Whiz, has died at age 91.

Traisman died Tuesday at the University of Wisconsin Hospital and Clinics following a heart attack, said his granddaughter Jenna Greene, of Chevy Chase, Md.

Traisman worked for Kraft Foods on the teams that created Cheez Whiz and individually packaged cheese slices in the 1950s. He became a division director of food research with responsibility for cheese and related projects. (H/T - Rachel)
