Laura Shapiro: Sliced wrapped bread first appeared in 1930, and that became the sandwich standard right away. They had the slicing technology before then, but they didn’t have the wrapping technology and the two had to go together.
Before sliced bread, the lunch literature is full of advice on social distinctions and the thickness of bread in sandwiches. You slice it very thick and you leave the crusts on if you’re giving them to workers, but for ladies, it should be extremely, extremely thin. Women’s magazines actually published directions on how to get your bread slices thin enough for a ladies lunch. You butter the cut side of the loaf first, and then slice as close to the butter as you possibly can.


The Automat replaced the box, and sometimes even the bread, with a brass-trimmed door, presenting each part of the meal in a space both glamorous and utilitarian. I think there's a connection between what I loved about Sandbox -- its tidiness, its regularity, its immaculate presentation -- and the qualities people liked in an automat. They perfected a formula (those recipe books describe egg salad down to the last chopped teaspoon) and as long as they kept it clean and high-quality, they prospered. Once upon a time, industrialized food was a safe harbor. And lunch wouldn't be lunch without the clock.Shapiro: Every Horn & Hardart location had a manager’s book, with the rules for doing every single thing — how to squeeze the orange juice, how much filling to put on each sandwich, how to treat your customers, and how often to throw out the coffee. All the food came from a central commissary, which was a block-large building on 50th Street, between 10th and 11th. They did nearly everything there, for economy of scale and for quality control, and then they had extremely precise instructions for anything that had to be made in store. The idea was that any Automat you went to, you would get precisely the same dish.
Federman: And you never saw the people preparing your food, which somehow made it seem more sanitary, as if strangers weren’t touching your lunch. In the exhibition, we show the mechanics, so you can peek backstage and see how it worked.
