On This Day: August 31

August 31 brings three very different thresholds into view: a shipyard agreement that gave workers an independent voice, a tiny solar car that made sunlight move a machine, and a Berlin stage work that turned satire into a worldwide musical language.

In July 1980, Poland's government raised food prices while limiting wage growth. At the Lenin Shipyard in Gdańsk, the dismissal of crane operator Anna Walentynowicz became the immediate spark for a sit-in strike. Former shipyard electrician Lech Wałęsa led the workers. 1

The protest might have ended as a local dispute. Instead, other workplaces joined it. An Inter-Enterprise Strike Committee drew up the 21 Demands, including the right to form independent trade unions, the right to strike, the release of political prisoners, and greater freedom of expression. The demands were written on wooden boards and displayed at Gate No. 2, where people brought food, medicine, money, flowers, and prayers to the workers inside. 2

On August 31, Wałęsa and Deputy Premier Mieczysław Jagielski signed the Gdańsk Agreement. The government accepted the principle of independent, self-governing trade unions and the right to strike. The agreement did not end Poland's crisis, and the authorities later imposed martial law. But it created Solidarity, which grew into a mass movement and helped make democratic change possible. 12

Eight thousand miles away, at a General Motors exhibition in Chicago in 1955, visitors saw a car that was only fifteen inches long. It was William G. Cobb's Sunmobile, described by HISTORY as the world's first solar-powered automobile. 3

The machine was a model, but the mechanism was real. Twelve selenium photoelectric cells turned sunlight into an electric current. That current powered a tiny motor, which turned the driveshaft and the rear axle by a pulley. The Sunmobile could not carry a person, and a mass-produced solar car still does not define the automobile market. But the demonstration placed photovoltaics inside the public imagination of transportation. 3

The object was small enough to hold in your hands. The question it raised was much larger: could a car draw its energy from the same light falling on the road ahead?

In Berlin on August 31, 1928, Bertolt Brecht and Kurt Weill opened The Threepenny Opera. The work adapted John Gay's much older The Beggar's Opera, but Brecht turned its thieves, pickpockets, and prostitutes into a sharp critique of respectable capitalism. The production also broke the comfortable wall between performers and audience. 4

Weill expected several of the numbers to become popular. He was right. The original production ran for more than four hundred performances, and the work later appeared in eighteen languages with more than ten thousand performances around the world. Its opening song, “The Ballad of Mackie Messer,” eventually travelled far beyond the theater as “Mack the Knife.” 4

A stage built to mock the social order became part of popular culture. The joke survived because the music made it memorable, and the music travelled because the joke still had teeth.

August 31 leaves us with three images: a worker at a shipyard gate, a miniature car catching the sun, and a theater audience watching criminals speak in the language of the respectable. Each begins as a limited opening. Each makes the world beyond it harder to keep closed.
