in 1882The "Elektromote" – forerunner of the trolleybus – is tested by Ernst Werner von Siemens in Berlin.
The Electromote was the world's first vehicle run like a trolleybus, which was first presented to the public on April 29, 1882, by its inventor Dr. Ernst Werner von Siemens in Halensee, a suburb of Berlin, Germany. The Elektromote operated from April 29 to June 13, 1882, on a 540 m (591 yard) trail-track starting at Halensee train station, and thence to “Straße No. 5”, today's Joachim-Friedrich-Straße, and “Straße No. 13”, today's Johann-Georg-Straße, crossing the Kurfürstendamm at the Kurfürstenplatz.
in 1903A 30 million cubic-metre landslide kills 70 in Frank, Alberta, Canada.
The Frank Slide is a natural landslide feature in the southern Rocky Mountains of Canada, and a significant historical event in western Canada. Frank, Alberta is a coal mining town in the Crowsnest Pass, Alberta. On April 29, 1903, at 4:10 a.m., 90 million tonnes (30 million cubic metres) of limestone crashed from the east face of Turtle Mountain and covered approximately three square kilometres of the valley floor. The slab of rock that broke free was approximately 650 m high, 900 m wide and 150 m thick. The slide dammed the Crowsnest River and formed a small lake, covered 2 km of the Canadian Pacific Railway, destroyed most of the coal mine's surface infrastructure, and buried seven houses on the outskirts of the sleeping town of Frank, as well as several rural buildings. Frank was home to approximately 600 people in 1903; it is estimated that 90 of the roughly 100 individuals in the path of the slide were killed. The town was evacuated, but people were soon allowed to return and both the mine and the railway were back in operation within a month. The town of Frank continued to grow, until a report on the mountain’s stability resulted in the provincial government ordering the closure of the south part of the town in 1911. Studies and monitoring continue today.
in 1945The Dachau concentration camp is liberated by United States troops.
Dachau concentration camp was the first of the Nazi concentration camps opened in Germany, located on the grounds of an abandoned munitions factory near the medieval town of Dachau, about 16 km (9.9 mi) northwest of Munich in the state of Bavaria, which is located in southern Germany. Opened 22 March 1933 (51 days after Hitler took power), it was the first regular concentration camp established by the coalition government of the National Socialist Party (Nazi Party) and the German Nationalist People's Party (dissolved on 6 July 1933). Heinrich Himmler, then Chief of Police of Munich, officially described the camp as "the first concentration camp for political prisoners."
