rford, the original Erie Canal ended at Albany; Lock 1 was located north of Colonie Street. The Canal emptied into a 32-acre (13 ha) man-made lagoon called the Albany Basin, which was Albany's main port from 1825 until the Port of Albany-Rensselaer opened in 1932. In 1829, while working as a professor at the Albany Academy, Joseph Henry, widely regarded as "the foremost American scientist of the 19th century", built the first electric motor. Three years later, he discovered electromagnetic self-induction (the SI unit for which is now the henry). He went on to be the first Secretary of the Smithsonian Institution.

This was the last time the city was one of the top ten largest urban places in the nation.

One of the ten companies that formed the NYCRR was the Mohawk and Hudson Railroad, which was the first railroad in the state and the first successful steam railroad running regularly scheduled service in the country.

Beverwyck Brewery, originally known as Quinn and Nolan (Nolan being mayor of Albany 1878�1883), was the last remaining brewer from that time when it closed in 1972. The city's location at the east
