What was the membership of IBEW in the year 1919?

The membership of the International Brotherhood of Electrical Workers (IBEW) in 1919 is documented to be 148,072. This substantial membership figure reflects the growth and impact of labor unions during a time of increased industrialization and worker organization in the early 20th century. The IBEW was formed in 1891, and by the end of World War I, labor unions, including the IBEW, had gained significant traction as they advocated for better working conditions, wages, and rights for electrical workers. This period marked a crucial development in the labor movement, leading to a higher level of union membership and increased political and social influence.
