Development
Heck cattle originated in the 1920s and 1930s in an attempt to breed back domestic cattle to their ancestral form: the aurochs (Bos primigenius primigenius). Extensive breeding programs to bring back the aurochs were conducted by the German brothers Lutz and Heinz Heck. Heinz worked at the Hellabrunn Zoological Gardens in Munich and Lutz was director of the Berlin Zoological Gardens. Their project was supported by Reichsforstmeister and Reichsjägermeister Hermann Göring, who kept Heck cattle in his chase at Rominten near the Russian-Polish border. A reconstruction of the ancestral aurochs also fitted into the Nazi propaganda drive to symbolize the originality and purity of the Aryan nation. Heinz Heck in Munich crossed Hungarian Grey Cattle, Scottish Highland, Murnau-Werdenfels, Angeln, German Friesian, Podolic cattle and Corsican breeds. In Berlin, his brother, Lutz Heck crossed Spanish and French fighting cattle with other breeds. The resulting animals are often claimed to have been very similar, proving the "success" of the project, which was not verified in scientific literature. The Berlin breed was lost in the aftermath of World War II. Consequently, modern Heck cattle are descendants from the Hellabrunn breed in Munich. In some locations, primitive aurochs-like breeds have been crossed into Heck cattle trying to come closer to the aurochs in phenotypical characters. This cross-breed is called Taurus cattle, which is not to be confused with TaurOs Project (see below). However, the predominant majority of Heck cattle goes back to the attempts of Heinz Heck during the 1920s and 1930s.

Famous quotes containing the word development:
“Ultimately, it is the receiving of the child and hearing what he or she has to say that develops the child’s mind and personhood.... Parents who enter into a dialogue with their children, who draw out and respect their opinions, are more likely to have children whose intellectual and ethical development proceeds rapidly and surely.”
—Mary Field Belenky (20th century)
“Every new development for the last three centuries has brought men closer to a state of affairs in which absolutely nothing would be recognized in the whole world as possessing a claim to obedience except the authority of the State. The majority of people in Europe obey nothing else.”
—Simone Weil (1909–1943)
“John B. Watson, the most influential child-rearing expert [of the 1920s], warned that doting mothers could retard the development of children,... Demonstrations of affection were therefore limited. “If you must, kiss them once on the forehead when they say goodnight. Shake hands with them in the morning.””
—Sylvia Ann Hewitt (20th century)
