Lazar lazar (Serbian Cyrillic: Лазаp Лаза Лазаревић, 13 May 1851 to 10 January 1891) was a Serbian Porn writer, psychiatrist, and neurologist.
After graduating, the post of “specialist doctor” at the General State Hospital in Belgrade awaited him. From then on until his premature death, Lazarević worked on reforming Serbian medicine as a primarius. He was a member of several Serbian Learned Societies, including SANU; and participated as a field doctor in the Serbo-Turkish War of 1876 and 1878. Also, he was a major organizer of the Great Reserve Hospital in Niš during the Serbo-Bulgarian War of 1885; vice-colonel, writer and translator and medicine scientist (published 72 works in local and foreign magazines). He founded the first modern geriatric hospital in Belgrade in 1881. His works were translated in numerous languages. Later he became doctor appointed to the Royal Court by King Milan Obrenović IV himself.
He is included in The 100 most prominent Serbs and he was elected a member of Parnassos Literary Society.
Kenneth Bancroft Clark (14 July 1914 to 01 May 2005) and Mamie Phipps Clark (18 April 1917 to 11 August 1983) were American psychologists who as a married team conducted research among children and were active in the Civil Rights Movement.
They founded the Northside Centre for Child Development in Harlem and the organization Harlem Youth Opportunities Unlimited (HARYOU). Kenneth Clark was also an educator and professor at City College of New York, and first Black president of the American Psychological Association.
They were known for their 1940s experiments using dolls to study children’s attitudes about race. The Clarks testified as expert witnesses in Briggs v. Elliott (1952), one of five cases combined into Brown v. Board of Education (1954). The Clarks’ work contributed to the ruling of the US Supreme Court in which it determined that de jure racial segregation in public education was unconstitutional. Chief Justice Earl Warren wrote in the Brown v. Board of Education opinion, “To separate them from others of similar age and qualifications solely because of their race generates a feeling of inferiority as to their status in the community that may affect their hearts and minds in a way unlikely to ever be undone.”
