The Story

In the Gilded Age, when American industry consolidated into vast corporations, Philadelphia's John G. Johnson became the era's preeminent corporate advocate, arguing well over a hundred cases before the U.S. Supreme Court on behalf of clients like the Pennsylvania Railroad, Andrew Carnegie, and J.P. Morgan. Working from his Walnut Street office, he shaped the legal fights over the new antitrust laws that tried to rein in those same industrial titans. A passionate collector, he amassed nearly 1,300 paintings that became a cornerstone of the Philadelphia Museum of Art.

Why it matters

Johnson embodies the age when corporate law and great private wealth reshaped both the American economy and its public institutions, leaving a legal and cultural legacy that outlived him.

In 1812 it became the first in the country to print Bibles from stereotyped plates, a technique that made books cheaper to produce and helped spread reading among ordinary people.
