Polish–Soviet War: A decisive Polish victory in the Battle of Komarów.

The Polish-Soviet War, which took place from 1919 to 1921, resulted in a Polish victory. The war was fought between Poland and Soviet Russia, along with its Bolshevik government. The conflict had multiple phases and was characterized by various military operations and battles. One of the most notable events during the war was the Battle of Warsaw, also known as the “Miracle on the Vistula,” which took place in August 1920. The Polish forces successfully repelled the Soviet offensive and managed to push the Soviet Red Army back.

The war concluded with the signing of the Treaty of Riga in March 1921. This treaty recognized Poland’s territorial gains and established a new eastern border between Poland and Soviet Russia. As a result, Poland retained control over most of the disputed territories and emerged as the victor in the conflict.

31 August 1888

Jack the Ripper’s first confirmed victim, Mary Ann Nichols is murdered.

On 31 August 1888, the body of a homeless women, brutally murdered and mutilated, was found in a Whitechapel backstreet. Here, as part of our ‘big day in history’ series, Dominic Sandbrook explores the discovery of Jack the Ripper’s first victim, Mary Ann Nichols.

As London’s bells rang in the last day of August 1888, rain was falling. It had been one of the wettest summers in living memory, and there was thunder in the air. On the horizon a fierce red glow seared the sky above Shadwell, where a huge fire had broken out in the dry dock.

Some time between one and two o’clock that morning, a woman called Mary Ann Nichols, known to her friends as ‘Polly’, was thrown out of the kitchen of the shabby lodging house at 18 Thrawl Street, Spitalfields. Fate had dealt Polly a rough hand. A 43-year-old mother of five children, she was separated from her husband and now drifted from one workhouse to another, scratching a meagre existence from handouts and casual prostitution.

Short of the four pence she needed to pay for a bed in the lodging house, Polly once more found herself on the street. “Never mind,” she said, gesturing at the velvet-trimmed straw bonnet she was wearing. “I’ll soon get my doss money. See what a jolly bonnet I’ve got now.” The implication was clear: she was heading back out to find a punter.

An hour or so later, Polly was seen by one of her roommates on the corner of Whitechapel Road, clearly drunk. She had made her doss money three times over, she boasted, but had already spent it on gin and was off to make some more.

That was the last time Mary Ann Nichols was seen alive. At 3.40am, a carter found her lying in the darkened doorway of a stable. Her throat had been slit and her body horribly mutilated. The murderer who would later be dubbed ‘Jack the Ripper’ had claimed his first victim.

Thomas Edison receives a patent for his movie camera, the Kinetograph. Edison had developed the camera and its viewer in the early 1890s and staged several demonstrations.

The camera was based on photographic principles discovered by still-photograph pioneers Joseph Nicephone Niepce and Louis Daguerre of France. In 1877, inventor Edward Muybridge developed a primitive form of motion pictures when Leland Stanford, governor of California, invited him to develop photo studies of animals in motion. Muybridge developed an ingenious system for photographing sequential motion, setting up 24 cameras attached to trip wires stretched across a racetrack. As the horse tripped each wire, the shutters snapped. The resulting series of photos could be projected as something resembling a motion picture. This breakthrough in the early 1870s inspired another student of animal motion, Etienne Jules Marey of France, to develop in 1882 a rotating camera rather like a rifle, where different pictures were taken in a rapid sequence by a rotating cartridge.

Unlike these earlier cameras, Edison’s Kinetoscope and Kinetograph used celluloid film, invented by George Eastman in 1889. In February 1893, Edison built a small movie studio that could be rotated to capture the best available sunlight. He showed the first demonstration of his films—featuring three of his workers pretending to be blacksmiths—in May 1893.

The invention inspired French inventors Louis and August Lumiere to develop a movie camera and projector, the Cinematographe, that allowed a large audience to view a film. Several other cameras and projectors were also developed in the late 1800s.

In 1898, Edison sued American Mutoscope and Biograph Pictures, claiming that the studio had infringed on his patent for the Kinetograph. He had entrusted the development of the machine to his assistant, W.L.K. Dickson, who left Edison’s company in 1895 and helped found Biograph. However, in 1902, the U.S. Court of Appeals ruled that although Thomas Edison had patented the Kinetograph, he only owned rights to the sprocket system that moved perforated film through the camera, not the entire concept of the movie camera.

In 1909, Edison and Biograph joined forces with other filmmakers to create the Motion Pictures Patents Company, an organization devoted to protecting patents and keeping other players from entering the film industry. In 1917, the Supreme Court dissolved the trust, and the Edison Company left the film industry the same year.
