G. Stanley Hall
Granville Stanley Hall (01 February 1846 to 24 April 1924) was a pioneering American psychologist and educator.
His interests focused on human life span development and evolutionary theory. Hall was the first president of the American Psychological Association and the first president of Clark University. A Review of General Psychology survey, published in 2002, ranked Hall as the 72nd most cited psychologist of the 20th century, in a tie with Lewis Terman.

After spending a period in the Faculty of Law, Güngör graduated from the Faculty of Literature and Social Sciences of Istanbul University in 1961. He received his Ph.D. in 1965 with a thesis titled “Kelâmî (Verbal) Yapılarda Estetik Organizasyon”. Kenneth Hammond invited him to visit the University of Colorado. He became an associate professor with his thesis titled “Şahıslar arası Ihtilafların Çözümünde Lisanın Rolü” in 1970. He became an academic in the Faculty of Literature and Social Sciences of Istanbul University in 1975. He eventually became the president of Selçuk University in 1982.
He mostly studied culture, personality, customs, people and religion. He focused on the identity and cultural problems which Turkish people have faced in the last 150 years.
