Achievements of Alan Mathison Turing (AMT) in computer science and informatics resemble those of Albert Einstein in physics. Turing’s contributions are presented through most important events and achievements, and in particular through the concept of hypercomputers. Several AI and human-intelligence related concepts are analyzed. A short text is devoted to Donald Michie, Turing's co-worker and contemporary, an honorary member of the Jozef Stefan Institute. Even though his centenary, Turing remains largely unknown to an average citizen of the world. An appeal for his full recognition is proposed.
