75 years ago the computer age started in Berlin. The structural engineer Konrad Zuse presented in 1941 in Berlin his "abacus" Z3. The Z3 was the first fully functional program-controlled computer in the world. In addition, he developed a universal algorithmic language "Plankalkül". On the occasion of the 75th anniversary of the first computer the "Zuse Institute Berlin" (ZIB) organizes on May 11 a festive Colloquium, entitled "The Digital Future".
