Marian J. Dudek, age 10, of Williamsport, Pa., for her question:

Who invented sandwiches?

Sandwiches must have been invented soon after people learned to bake loaves of bread and roast beef. If we forgot the wonderful trick, no doubt it would be invented all over again. We cannot name all the sandwich inventors of history or give them the medals they deserve, but we do know for whom the sandwich was named.

He was John Montagu, an 18th century English Earl of Sandwich. A group of islands were named for him. The busy Earl served as postmaster general, secretary of state and twice as first lord of the admiralty. This Earl of Sandwich was fond of sandwiches and tried to make them popular, which is why peop1e associate them with his name.
