Wirth designed many languages, including Euler, Algol W, Pascal, Modula, and Oberon, but he did not design Algol; more specifically, he did not design Algol 60. Instead, a committee (J. W. Backus, F. L. Bauer, J. Green, C. Katz, J. McCarthy, P. Naur, A. J. Perlis, H. Rutishauser, K. Samelson, B. Vauquois, J .H. Wegstein, A. van Wijngaarden, and M. Woodger) designed it, and Peter Naur edited the remarkable Algol 60 specification. A few others, including Edsgar Dijkstra, who completed the first implementation, participated in meetings leading up to the final design.
