About Rainer Grimm

Rainer Grimm, the founder and creator of this blog, was a highly respected C++ expert, software architect, team lead, and instructor. He began teaching training courses in 2002 and, in 2011, published the first worldwide C++11 book. Since then, he authored eight additional C++ books, translated into five languages.

Since 2016, he worked as an independent instructor, passionately combining learning and teaching. In a typical year, he delivered 40 to 50 seminars on modern C++ and Python, participated in around 10 conferences, and provided presentations and workshops.

Unfortunately, Rainer Grimm passed away in October 2025. The blog is now maintained by a collective of C++ experts who were close friends of Rainer Grimm and is administratively supported by the Grimm family. Through their efforts, his legacy continues, providing a valuable resource for developers and enthusiasts of modern C++.

Rainer Grimm, a beloved C++ expert, author, and mentor, passed away on October 6, 2025. Rest in peace.
