Abstract: Bridges are one of the classic engineering structures of which several have survived from the ancient times. Scour of bridge piers is one of the issues that may result in bridge failure. The causes of pier scour were investigated relatively late, because only laboratory observations indicated the complex scour pattern experienced in typical sand bed rivers. The following would like to give a review on the first century of bridge pier scour with a twofold approach: (1) Presentation of main papers with a short summary of the results elaborated, and (2) Introduction of the individuals behind the research with a short biographical note. Most of the authors to be presented are known to the hydraulic community, yet few may be familiar with his origin, his education, his professional career and the decorations presented for outstanding works. The biographies are also illustrated with the portrait of the individual.
