Robert Goddard and the beginnings of modern rocketry

Connect a rocket experiment in Auburn, Massachusetts, to the history of spaceflight. Look for testing, changes, and teamwork. Rocket experiments use hazardous equipment; our classroom challenge is to draw and explain an idea, not build or ignite a rocket.

1847–1922

Alexander Graham Bell

Boston

In Boston on March 10, 1876, Bell spoke words that his assistant Thomas Watson heard through their experimental telephone. Their work helped people communicate across distances. Bell worked within a wider history of inventors exploring sound and electricity; inventions rarely come from one person working entirely alone.

1874–1937

Guglielmo Marconi

South Wellfleet, near Marconi Beach

Marconi was an Italian inventor who developed wireless communication. In 1903 his South Wellfleet station sent a message from President Theodore Roosevelt across the Atlantic. The nearby beach preserves his name. This was a Cape Cod milestone, not Marconi’s first experiment with wireless signals.

1894–1970

Percy Spencer

Raytheon in Massachusetts

While working on radar equipment, Spencer noticed that microwaves could heat food. He and other Raytheon engineers developed microwave cooking equipment. Their work links a Massachusetts company to a familiar kitchen appliance. Studying an unexpected result can lead to a new question and a new invention.

1890–1974

Vannevar Bush

MIT in Cambridge; Raytheon co-founder

Bush was an engineer who worked on early computing at MIT and helped found the company later known as Raytheon. Its early work included radio technology. His career connects laboratories, companies, and government research. Large technical changes depend on many people with different kinds of skill.

Margaret E. Knight

Springfield

Knight designed a machine to cut, fold, and glue paper into flat-bottomed bags. She worked in Springfield and defended her right to the invention. A patent is a legal protection for an invention. Her work changed a common object that people could use every day.
