Bradley was born in Milwaukee, Wisconsin, the eldest son of Henry Clay Bradley and Clara Blanchard Lynde, and attended Milwaukee Public Schools.
[1] "In 1901, Lynde was working for Milwaukee Electric when he came up with an idea for improving the controllers that regulate motor speed.
He quit his job, secured a $1,000 investment from Dr. Stanton Allen, and founded the Allen-Bradley Company.
Harry joined his brother three years later, and together they turned a two-man shop into a major center of industry.
Shortly before his death, plans were made to create a foundation, and the Lynde Bradley Foundation was established by his estate soon after his death.
