Nada Inada (なだ いなだ, 08 June 1929 to 06 June 2013) was the pen-name of a Japanese psychiatrist, writer and literary critic active in late Shōwa period and early Heisei period Japan. His pen name is from the Spanish language phrase “nada y nada”.
Nada was born in the Magome district of Tokyo, but was raised for part of his youth in Sendai. He graduated from the Medical School of Keio University. One of his fellow students was Kita Morio, who encouraged his interest in literature and in the French language. He later travelled to France on a government scholarship. His wife was French.
Nada’s medical specialty was psychiatry, particularly in the treatment of alcoholism, and he was head of the Substance Abuse Department of National Hospital located in Yokosuka, Kanagawa.
One of his early novels, Retort, was nominated for the prestigious Akutagawa Prize.
Jonathan Potter (born 08 June 1956) is Dean of the School of Communication and Information at Rutgers University and one of the originators of discursive psychology.
In 1984 he published Social Texts and Context: Literature and Social Psychology with Margaret Wetherell and Peter Stringer. This collaboration was developed in parallel to Potter and Wetherell’s PhD work.
Abraham Harold Maslow (01 April 1908 to 08 June 1970) was an American psychologist who was best known for creating Maslow’s hierarchy of needs, a theory of psychological health predicated on fulfilling innate human needs in priority, culminating in self-actualisation.
Maslow was a psychology professor at Brandeis University, Brooklyn College, New School for Social Research, and Columbia University. He stressed the importance of focusing on the positive qualities in people, as opposed to treating them as a “bag of symptoms”. A Review of General Psychology survey, published in 2002, ranked Maslow as the tenth most cited psychologist of the 20th century.
Thorleif Schjelderup-Ebbe (12 November 1894 to 08 June 1976) was a Norwegian zoologist and comparative psychologist.
Thorleif Schjelderup-Ebbe was, at the age of 19 (in 1913), the first to describe a pecking order of hens. He based findings on an interest in observing chickens at a farm where he spend his summer holidays. The dominance hierarchy of chickens and other birds that he studied led him to the observation that hens had an established social order determining who dared to peck whom in a fight. This order was, Schjelderup-Ebbe concluded, not necessarily dependent on the strength or age of the hens, and not necessarily a strict ranking as he even observed triangles of dominance. Schjelderup-Ebbe studied for a Ph.D. in Germany, tried to present his thesis in Oslo, but was rejected.
