Steel was first made at outside of Baltimore at Sparrows Point in 1889, by the Pennsylvania Steel Company. By the mid-20th century, Sparrows Point was the world's largest steel mill, stretching four miles from end-to-end. The mill employed tens of thousands of workers. It used the traditional open-hearth steelmaking method to produce ingots, a labor—and energy—intensive process.

Purchased by Bethlehem Steel in 1916, the mill's steel ended up as girders in the Golden Gate Bridge and in cables for the George Washington Bridge, and was a vital part of war production during World War I and World War II. The mill was serviced by Four railroads: the Western Maryland, Pennsylvania, Baltimore & Ohio and yard work was done by the Patapsco & Back River RR.
Some of our Betlehem steel is celebrating an anniversary this weekend.

Beacon in the bay: Golden Gate turns 75
It is the 75th anniversary of the Golden Gate Bridge, and to honor the iconic structure, project Solar Beacon was unleashed. Solar Beacon is an art installation that sits atop the bridge's towers and shines two lights "that are bright as the sun, but much smaller in size," across the Bay Area. People can log onto the Solar Beacon website and schedule their own personal show by designating where they would like the lights to shine.
"During the 75th Anniversary celebrations and the months that follow, the solar beam will directly link the line of sight between the public and the bridge they love," the project's website reads.
LIFE: 75 years of the Golden Gate
Solar Beacon is a feat of art and science, similar to the "International Orange" suspension bridge itself. Construction of the Golden Gate Bridge took four years and claimed the lives of 11 men. It nearly took the lives of 19 more whose fates were changed by a safety net installed under the bridge for workers. These 19 came to be known as the "Half-way-to-Hell Club."
Despite it's gruesome underpinnings, the bridge was heralded for its aesthetics upon its opening to the public in 1937 - prompting the San Francisco Chronicle to call it a "Thirty-five million dollar steel harp!"
The Golden Gate bridge has become a meaningful destination for Bay Area residents—many of whom will celebrate the anniversary at a festival today.
And, from Baltimore, we remeber—and honor—our contribution and we wish all Golden-Gaters well.
