Ampere Street

From Pittsburgh Streets
Ampere Street
Neighborhood Hazelwood
Origin of name Ampere, unit of electric current

Ampere Street, along with nearby Electric Street and Volt Alley (today Steele Court), was laid out by Thomas S. Blair (1825–1898) in the 1890s.[1][2][3] Its name comes either from the ampere, the unit of electric current, or from the French physicist and mathematician André-Marie Ampère (1775–1836), who was instrumental in the early scientific study of electromagnetism and for whom the electrical unit is named. But considering that the nearby alley was named Volt and not Volta, the street is most likely named for the unit and not (directly) for the scientist. On the other hand, Bob Regan includes "Ampere" in a list of streets named for noted historical people.[4] See Electric Street for more about Blair and his interest in science and engineering.
