From 1897 Hahn studied chemistry at Marburg and Munich, taking his doctorate examination in 1901 at Marburg and submitting to Professor Theodor Zincke a thesis on organic chemistry. In 1913 Hahn married Edith, née Junghans and they had one son, Hanno, born in 1922, killed by accident in 1960
Hugo Junkers (3 February 1859 – 3 February 1935) was an innovative German engineer, as his many patents in varied areas (gas engines, aeroplanes) show. In 1915, he pioneered the first great change in aviation materials and design technology, away from wood and fabric materials braced by wire rigging, towards all-metal, cantilever-winged monoplane aircraft that had little to no external bracing.
Hugo Junkers is mainly known in connection with aircraft bearing his name. This includes such he reluctantly developed for the German Empire during World War I, later in minor association with Anthony Fokker, as well as civil aircraft designs during the Interwar Period produced by Junkers Flugzeugwerke (Junkers Aircraft Works). Junkers, a pacifist and not on good terms with the Nazis, died in 1935 and was not involved in the development of Junkers military aircraft for the Third Reich's Luftwaffe before or during World War II.
Richard Hellmann: Hellmann's (Blue Ribbon) Mayonnaise, 1905.
Alzheimer was born in Marktbreit, Bavaria. His father served in the office of notary public in the family's hometown. In 1901, Alzheimer observed a patient at the Frankfurt Asylum named Auguste Deter. The 51-year-old patient had strange behavioral symptoms, including a loss of short-term memory. This patient would become his obsession over the coming years. In April 1906, Mrs. Deter died and Alzheimer had the patient records and the brain brought to Munich where he was working at Kraepelin's lab. In mid-December 1915, Alzheimer fell ill on the train on his way to the University of Breslau, where he had been appointed professor of psychiatry in 1912. Most probably he had a streptococcal infection and subsequent rheumatic fever and kidney failure. He died of heart failure at the age of 51 in Breslau, Silesia. ALzheimer was a German psychiatrist and neuropathologist and a colleague of Emil Kraepelin. Alzheimer is credited with identifying the first published case of "presenile dementia", which Kraepelin would later identify as Alzheimer's disease.
Wernher von Braun(inventor) and Walter Robert Dornberger (co-inventor): (6 September 1895 - 27 June 1980) was a German Army artillery officer whose career spanned World Wars I and II. He was a leader of Germany's V-2 rocket program and other projects at the Army Research Center. The V2 rocket was a single-stage rocket fueled by alcohol and liquid oxygen. It stood 46.1 feet high and had a thrust of 56,000 pounds. The A-4 had a payload capacity of 2,200 pounds and could reach a velocity of 3,500 miles per hour. It was the world's first launch of a ballistic missile and the first rocket ever to go into the fringes of space.
Albert Einstein was born March 4 1879 and died April 18 1955) was a German-born theoretical physicist who developed the theory of general relativity, effecting a revolution in physics. For this achievement, Einstein is often regarded as the father of modern physics and one of the most prolific intellects in human history. He received the 1921 Nobel Prize in Physics for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect". The latter was pivotal in establishing quantum theory within physics. The word Einstein now is related with genius. Einstein merited awards and honors, including the Nobel Prize in Physics.

General relativity and the Equivalence Principle
General relativity (GR) is a theory of gravitation that was developed by Albert Einstein between 1907 and 1915. According to general relativity, the observed gravitational attraction between masses results from the warping of space and time by those masses. General relativity has developed into an essential tool in modern astrophysics. It provides the foundation for the current understanding of black holes, regions of space where gravitational attraction is so strong that not even light can escape.

CAR INDUSTRY
In 1916 BMW was founded, but didn't start auto production until 1928. The collapse of the global economy during the Great Depression in the early 1930s plunged Germany's auto industry into a severe crisis. While eighty-six auto companies had existed in Germany during the 1920s, barely twelve survived the depression, including Daimler-Benz, Opel and Ford's factory in Cologne. In addition, four of the country's major car manufacturers — Horch, Dampf Kraft Wagen (DKW), Wanderer and Audi — formed a joint venture known as the Auto Union in 1932, which was to play a leading role in Germany's comeback from the depression.
Currently, six German companies dominate the automotive industry in the country: Volkswagen AG, BMW AG, Daimler AG, Dr. Ing. h.c. F. Porsche AG, Adam Opel AG and Ford-Werke GmbH. Nearly six million vehicles are produced in Germany each year, and approximately 5.5 million are produced overseas by German brands.
Germany is one of the top 4 automobile manufacturers in the world. The Volkswagen Group is one of the three biggest automotive companies of the world
