Bernhard Möller, born in 1969, studied mathematics and physics at Bielefeld University after earning his high school diploma in 1989.
During his studies, he worked on the SAP/R3 migration project for Bertelsmann/Sonopress and later began working as a freelance instructor in mathematics and physics. The experiences he gained from his transition from high school to university, combined with those from his later work as a lecturer, motivated him to write a textbook on calculus designed to ease the transition from high school to university-level mathematics for prospective students.
To this day, he continues to work as a lecturer and also serves as a private tutor.
