Grimsehl studied physics and mathematics in Hanover and worked as an assistant teacher at the Johanneum School of Scholars in Hamburg from 1885 . In 1892 he was a teacher in Cuxhaven . In 1909 he published the textbook for physics . This book established his reputation as a physics teacher and was published in new editions for decades. There was a translation into English and even a Chinese edition in 1954. In 1908 he became the first director of the newly founded Uhlenhorst-Barmbek grammar school. In 1910, Grimsehl took part in the world exhibition in Brussels and demonstrated school exercise equipment there. His demands on the students were expressed in a speech when he said: “Those who are not satisfied with average performance always find their place in life; the world is only full on average people. "
As much as Grimsehl encouraged modern pedagogical methods in science lessons such as independent student experiments, he was also a patriot and convinced of military virtues that, at the age of 53, he volunteered for military service after the outbreak of World War I and three months later in the Died as a captain near Langemark in October 1914 .
One of Grimsehl's closest collaborators was the textbook author Karl Hahn (1879–1963), who received his doctorate in physics and was awarded an honorary doctorate from the University of Gießen in 1959. He came to the Oberrealschule auf der Uhlenhorst in 1912, mediated by Grimsehl, and was elected headmaster there in 1920 (Hahn joined the Nazi teachers' association in 1935 and soon afterwards became the realm physics clerk). Its school books were used in the classroom well into the 1960s.
