This is Kano Jigoro (10 December 1860 - 4 May 1938), the founder of judo. Back in the day, Kano was practicing and teaching the martial arts of jujutsu along with his former teachers, usually being thrown and losing most of his training fights. This motivated him to study certain movement patterns a long time, which resulted in finding new ways of breaking the posture of the opponent. When he presented the results of his study to one of his former teachers, he approved, which led Kano to found his own school and publish the essentials of his new system. He named his system 'judo' which is a combination of jū (柔), meaning 'pliancy', and dō, which means literally 'The Way'. That is the reason why the martials arts of judo is often referenced as 'The Gentle Way'.

One of the key values in Judo is respect. Although judo is a competitive sport, the safety and respect towards your partner or oponent should always have top priority. The key idea of practicing judo is not always striving to win a fight, but to grow together with your partner in training and to take care of each other, especially when you are fighting against each other in a randori, which is the Japanese term for a training fight. That means that you and your partner should both get the opportunity to practice different techniques like throws and grab handles or to try new ones that you learned in training.
