Ways to celebrate

Congress has actually weighed in on who invented the hamburger — a rare case of the federal government settling a food origin dispute.

Meet the officially recognized inventor

In 1900, Louis Lassen of Louis' Lunch in New Haven, Connecticut served a rushed customer a broiled ground beef patty between two slices of bread — in 2000, U.S. Representative Rosa DeLauro pushed through legislation officially crediting Lassen, and the Library of Congress recorded him as the creator of the first American hamburger.

Know the name traces to Germany

The dish's name comes from "Hamburg steak," a seasoned ground beef patty popular in 19th-century Hamburg, Germany, which German immigrants brought to the U.S. in the 1840s and 1850s decades before anyone put it on a bun.
