Süleyman Hüsnü Pasha: Commander of the military college and one of the coup plotters that organized the deposing of Sultan Abdülaziz.
Süleyman Pashazade Sami: The son of the coup plotter Süleyman Hüsnü Pasha, he served as the Minister of Education and as the rector of the Istanbul University. He prepared guidelines for primary schools, and worked on children's education with a project named 'Education and Training of Children'.
Beşir Fuad: Had a materialist worldview. As the mentor of Abdullah Cevdet, Baha Tevfik, Ahmet Nebil and Celal Nuri, he was responsible for their materialist views. He introduced social Darwinism to the Ottoman Empire, which was one of the basic ideologies of Young Turks during the Abdul Hamid II rule. Beşir Fuad was heavily influenced by evolutionist/materialist thinkers such as Claude Bernard and Ludwig Büchner. He committed suicide at the age of 35 and wrote down how he felt as he slipped away. He said that he did this to leave a scientific understanding as to what one feels at time of death. This suicide created shock waves in the Ottoman society, which up to that point was quite unfamiliar with the concept of suicide, and triggered a suicide trend in Istanbul.
Baha Tevfik:Became an evolutionist at the School of Political Sciences during the reign of Abdul Hamid II. He argued for unconditional Westernization. In an article he wrote for the journal Felsefe (Philosophy), he claimed that a philosopher had to be a scientist and definitely a materialist. To him metaphysics was 'empty and negative' and contradicted science. In his book Hassasiyet Bahsi ve Yeni Ahlak (Issue of Sensitivities and New Morality), he rejected religious moral values. His so-called solution for the future of the humanity was communism and anarchy. He believed that the future could be revived with scientific anarchy.
Hüseyin Hilmi:It is reported that he got his communist ideals from Baha Tevfik. In the journal İştirak (The Participation) that he published in 1910, he wrote several pieces on Marxism.
Subhi Edhem:A teacher of history of nature, he was also an author at Servet-i Fünun (Wealth of Knowledge). Taught Lamarckism and Darwinism during his lectures.
Ethem Nejat:Became an evolutionist together with Baha Tevfik. He was also writing for İçtihad (The Opinion) magazine of Abdullah Cevdet. He was the founding general secretary of the Communist Party of Turkey.
