The Story

In a Southbridge factory that had ground spectacle lenses and precision optics for more than a century, a team led by physicist Elias Snitzer achieved a breakthrough that would reshape modern communication: the world's first working optical fiber laser, soon followed by the first fiber amplifier. American Optical's sprawling complex had long been a center of glassmaking expertise, and in the early 1960s that craft helped turn a thin strand of doped glass into a device that could generate and boost light itself. Recognized here as an IEEE Milestone, the work carried out between 1961 and 1964 quietly laid the foundation for an entire industry.

Why it matters

The fiber lasers and amplifiers pioneered on this site became the backbone of global telecommunications and the internet, making a small New England mill town an unlikely birthplace of the information age.

Swasey Parkway

Exeter, NH

Swasey Parkway runs along the tidal Squamscott River in Exeter, the gift of native son Ambrose Swasey, an inventor and machine-tool maker who was born here in 1846 before making his fortune building precision instruments and astronomical telescope mounts. Dedicated in 1930, the riverside promenade was his way of giving something lasting back to the New Hampshire town of his childhood. More than ninety years on, it endures as a green civic space where residents still stroll, gather, and watch the river slip past.

Swasey Parkway — Gift of Ambrose Swasey

Exeter, NH

This riverside parkway along the Squamscott River was a 1931 gift to the town of Exeter from Ambrose Swasey, a New Hampshire-born mechanical engineer and industrialist who rose from a Northfield farm to co-found the Warner & Swasey Company of Cleveland. That firm became famous for precision machine tools and for building some of the era's great astronomical telescopes, and Swasey channeled the fortune he earned into philanthropy for his native state. In dedicating the parkway he gave Exeter a lasting stretch of public green space where the town could gather along the water.

First Plastic

City of Albany, NY

In 1868, Albany inventor John Wesley Hyatt was chasing a $10,000 prize offered for a substitute for increasingly scarce ivory billiard balls. His answer was celluloid — a moldable material made from nitrocellulose and camphor that is widely regarded as the first commercially successful synthetic plastic. Produced here by the Albany Billiard Ball Company, it turned a parlor-game shortage into the opening chapter of the modern plastics age.

1BCG

Greenwich, CT

In the winter of 1921, radio was still a young and unruly science, and most experts believed the long waves were the only way to reach across oceans—leaving the crowded short waves to amateurs. On December 11 of that year, a small experimental station built by members of the Radio Club of America transmitted from this corner of Greenwich and was heard clear across the Atlantic in Ardrossan, Scotland. The feat proved that short waves, far from being useless, could carry signals immense distances with modest power.
