Zhou (or Jow) Tong ( and 周侗; pinyin: Zhōu Tóng) (died late 1121 CE) was the archery teacher and second military arts tutor of famous Song Dynasty general Yue Fei.
 Originally a local hero from Henan, he was hired to continue Yue Fei's military training in archery after the boy had rapidly mastered spearplay under his first teacher.
 In addition to the future general, Zhou accepted other children as archery pupils.
 During his tutelage, Zhou taught the children all of his skills and even rewarded Yue with his two favorite bows because he was his best pupil.
 After Zhou's death, Yue would regularly visit his tomb twice a month and perform unorthodox sacrifices that far surpassed that done for even beloved tutors.
 Yue later taught what he had learned from Zhou to his soldiers and they were successful in battle.
Abraham ben Raphael Caro was an Ottoman rabbi.
 He flourished at Adrianople in the first half of the eighteenth century.
 He was a descendant of Rabbi Joseph Karo, and was the stepson and pupil of Rabbi Eliezer ben Jacob Nachum, author of "Chazon Nachum" (Constantinople, 1743–45), whom he probably succeeded as rabbi of Adrianople.
 Several treatises written by Rabbi Abraham Caro and quotations from others of his works, none of which was published separately, are to be found in his stepfather's work.
 Abraham Caro died young.
Sigmund Freud ( ; ] ; born Sigismund Schlomo Freud; 6 May 1856 – 23 September 1939) was an Austrian neurologist and the founder of psychoanalysis, a clinical method for treating psychopathology through dialogue between a patient and a psychoanalyst.
 Freud was born to Galician Jewish parents in the Moravian town of Freiberg, in the Austrian Empire.
 He qualified as a doctor of medicine in 1881 at the University of Vienna.
 Upon completing his habilitation in 1885, he was appointed a docent in neuropathology and became an affiliated professor in 1902.
 Freud lived and worked in Vienna, having set up his clinical practice there in 1886.
 In 1938 Freud left Austria to escape the Nazis.
 He died in exile in the United Kingdom in 1939.
Edward George Glover (13 January 1888 – 16 August 1972) was a British psychoanalyst.
 He first studied medicine and surgery, and it was his elder brother, James Glover (1882–1926) who attracted him towards psychoanalysis.
 Both brothers were analysed in Berlin by Karl Abraham; indeed, the 'list of Karl Abraham's analysands reads like a roster of psychoanalytic eminence: the leading English analysts Edward and James Glover' at the top.
 He then settled down in London where he became an influential member of the British Psycho-Analytical Society in 1921.
 He was also close to Ernest Jones.
Franz Gabriel Alexander, in Hungarian "Alexander Ferenc Gábor", was born in Budapest in 1891, his father was Bernhard Alexander, a philosopher and literary critic, his nephew was Alfréd Rényi, a Hungarian mathematician who made contributions in combinatorics, graph theory, number theory but mostly in probability theory.
 Alexander studied in Berlin; there he was part of an influential group of German analysts mentored by Karl Abraham, including Karen Horney and Helene Deutsch, and gathered around the Berlin Psychoanalytic Institute.
 'In the early 1920s, Oliver Freud was in analysis with Franz Alexander' there — Sigmund Freud's son — while 'Charles Odier, one of the first among French psychoanalysts, was analysed in Berlin by Franz Alexander' as well.

Svend Bayer (born 2 January 1946 in Uganda to Danish parents) is a studio potter described by Michael Cardew as "easily my best pupil."

Karl Abraham (] ; 3 May 1877 – 25 December 1925) was an early important and influential German psychoanalyst, and a collaborator of Sigmund Freud, who called him his 'best pupil'.
The Berlin Psychoanalytic Institute (later the Göring Institute) was founded in 1920 to further the science of psychoanalysis in Berlin.
 Its founding members included Karl Abraham and Max Eitingon.
 The scientists at the institute furthered Sigmund Freud's work but also challenged many of his ideas.
