Who is credited with founding the NBEW through nationwide organizing efforts?

The founder of the National Brotherhood of Electrical Workers (NBEW) is indeed Henry Miller. Miller played a pivotal role in organizing electrical workers and establishing the NBEW as a significant labor union dedicated to improving the working conditions and rights of its members. His efforts were part of a larger movement during the early 20th century when many labor organizations were forming to better advocate for workers' interests across various trades.

Miller's contributions were critical in mobilizing workers at a national level, fostering a sense of unity and purpose among electricians, and negotiating for better wage standards and working conditions. The successful establishment of the NBEW represented an important step in the labor movement, particularly in trades that were still emerging during that time.
