The Foundation of
Market Street

The Houghton family legacy started in 1851, when Amory Houghton Sr. founded a small glass business, now known as Corning Incorporated. For over 170 years, Corning has enjoyed a heritage of innovation that has benefited both science and humanity, leaving a lasting impression of historical significance. 

Market Street was founded on the same principles of optimism and ingenuity, growing and evolving alongside the Houghton family for decades.

A Shared History of Innovation


The Corning legacy begins with the invention of the bulb-shaped glass encasement of Thomas Edison’s new lightbulb.


The  family office is founded to support the needs of the Houghton family.


Dr. Jesse Littleton, a Corning physicist, asks his wife to bake a cake on a piece of heat resistant glass developed in 1908, resulting in the successful launch of PYREX® glass. 


Corning revolutionizes the television industry by establishing a process to mass produce TV picture tubes. 

1960 - 1970

Inventions from Corning enable the first American manned spacecraft with heat resistant windows and transform how people connect using technology with fiber optic cables.
