Michael Grzimek was the second son of Bernhard Grzimek and Hildegard Prüfer.
Already as a child, he assisted his father in his research of wolves and dogs.
He spent the last years of the Second World War with his mother and his older brother Rochus on an old farm in Allgäu, which his father had bought in the 1930s.

At 16, he accompanied his father on an expedition to Ivory Coast.
The success that followed his father's book Kein Platz für wilde Tiere (No room for wild animals), which describes their 1954 Congo expedition, made Michael persuade his father to make a colour film based on it.
Although they had to borrow over 10 000 German marks, to make it and they thought it would be unsuccessful, as the film portrayed animals as peaceful (at that time an unusual thing ), the film unexpectedly won two Golden Bears (one as viewers' favourite film and the other from the International panel of academics) at the 1956 Berlin International Film Festival and was sold to 63 countries (including the Eastern bloc, China and Japan) and grossed a lot of money worldwide.
It also won another award, the Bundesfilmpreis.
The Grzimeks' offered their profits to extend the Serengeti.
Peter Molley, the director of the Tanganyikan national parks, suggested that the money would be better spent making a new survey of the number of wild animals and their migration routes so that the borders of the Serengeti could be better established.

During these vast explorations (which also served Michael as a preparation for a university degree), these routes were mapped precisely for the first time, and the number of the animals in their herds could be counted.
It was 367 000, one third of the expected number.
Both Grzimeks had to get a pilot license and buy a plane, a Dornier Do 27.
To make it look natural to the animals, they painted it with a zebra stripes pattern.
The code of the plane was D-ENTE. ("
D" stood for Germany, "E" for single engine light aircraft; they could choose the other three letters, and, as they wanted an animal name, they chose "ente", German for "duck".
Bernhard Grzimek joked that they could also have used "esel", German for "donkey", if they had thought of it then.)
