Founded in Pittsburgh by Grant McCargo in 1885, this plant became a major producer of the lubricating grease that kept American industry, railroads, and machinery running. Its most storied contribution came during World War II, when it supplied five million pounds of "Eisenhower grease" deemed vital to the war effort. Absorbed into Standard Oil of New Jersey after 1929, the works kept operating until 1999 — more than a century of quiet but essential industrial labor.

Frank E. Bolden was one of the first two African American war correspondents accredited by the U.S. Army during World War II. Reporting from India, Burma, and China, he chronicled the service of the "Buffalo Soldiers" and the celebrated Tuskegee Airmen for readers back home. He later became city editor of the Pittsburgh Courier, one of the nation's most influential Black newspapers.

This plaque marks the home of Michael A. Musmanno, a Pittsburgh-area jurist whose career stretched from the coal-country courtrooms of the 1920s to the world stage. He served in both World Wars, sat in the state legislature, and in 1947–48 presided over one of the Nuremberg trials that held Nazi leaders to account for their crimes. He capped his life with sixteen years on the Pennsylvania Supreme Court and authorship of sixteen books, and was laid to rest at Arlington National Cemetery.

Helen Richey of McKeesport broke into the sky in 1934 when she became the first woman to fly a commercial airliner — only to face such hostility from male colleagues that she resigned within a year. Undeterred, she became the first woman licensed as an instructor by the Civil Aeronautics Authority. When war came she rose to command the American wing of Britain's Air Transport Auxiliary, flew with the Women's Airforce Service Pilots, and finished the war a Major.
