Based on my discussions and correspondence with Professor Teodorescu, and with others who know him, I present this homage book about Professor Teodorescu, on his 83rd birthday. Professor Petre P. Teodorescu is a great European personality in the fields of mathematics and mechanics, with a charming life history, which it is important to be known not only by specialists. For this reason we wrote this book for the general public, with only few technical details at this time, including numerous enchanting photographs taken at conferences and with other occasions, as well as notes about ideas and events from the last 83 years. I want to thank my wife Sophia for her continuous help and assistance. We wish all our distinguished readers good reading, and great enjoyment while discovering this great European personality, from whom many valuable lessons can be learned.
