You probably didn't know her name, but Dorcas Reilly has been a part of our lives for a long time. She's credited with inventing the green bean casserole.

Back in 1955, Dorcas was working as a Campbell Soup Kitchen supervisor when she needed to whip up a dish for an Associated Press feature. She mixed cream of mushroom with frozen green beans and topped them with crunchy fried onions. Ever since, green bean casserole has been a staple of Midwestern Thanksgiving dinners.

While the green bean casserole is her most popular creation, Dorcas also came up with a tomato soup meatloaf, a tuna noodle casserole, and souper burgers. Basically she's responsible for a whole bunch of "old family recipes" that people use.

Sadly she passed away on October 15th at the age of 92 due to Alzheimer's disease.
