Bert Bally has had an extraordinary scientific career that he is still pursuing very actively.
     Born in The Hague, The Netherlands, he spent his early years in Indonesia, Italy, and Switzerland. At the University of Zurich (where he specialized in paleontology) he wrote his PhD thesis on the mapping of an area in the Central Apennines.
     For a major part of his career, Bert worked for Shell Oil. While with Shell Canada, he spent several summers mapping the Rocky Mountains and foothills of Alberta. Later he became their chief geologist, then transferred to Shell USA and progressed from manager of geologic research to chief geologist to senior consultant. In 1981 he joined Rice University as chairman of the Department of Geology and Geophysics. He was also appointed the Harry Carothers Weiss Professor of Geology, a position he still occupies.
     Early in his career, Bert realized the importance of seismic reflection records and expertly combined his love of geologic mapping with his curiosity about regional geology through detailed analysis of seismic reflection records. He is considered the world's leading expert in using seismic records in interpreting regional geology, especially in the area of folded mountain belts.
     Bert's impressive list of publications includes his paper, coauthored with Gordy Steward, on the structure and orogenic evolution of the southern Canadian Rocky Mountains (1966) in which he established (1) the role of regional seismic data in understanding fold belts, (2) that fold belts overlie vast monoclines of underlying foreland basement, (3) the justification for balanced cross sections, (4) the reintroduction of listric normal faulting, and (5) the importance of the relationship of foredeep subsidences to activities in the folded belt.
     With T. Cook he published a Stratigraphic Atlas for North and Central America (1975) which, in more than 250 maps, shows the Phanerozoic stratigraphy of North America. Most geologists are familiar with Bally's work through his two three-volume sets of seismic atlases (1983) that popularized the use of industrial reflection techniques for scientific purposes. As a counselor with the Geological Society of America, he proposed the DNAG project, a large multivolume encyclopedia on the geology of North America, for the GSA centennial celebration. With Peter Palmer, he edited the introductory volume, which many consider the most comprehensive introduction to the geology of North America.
     At Rice University, Bert has successfully built bridges between academia and industry. His worldwide recruiting brings together students from various national oil companies, and they in turn bring their data (seismic records, well logs, etc.). Bert spends countless hours working with them, often synthesizing data of the study areas.
     Bert has received numerous honors, including the William Smith medal (London Geologic Society), the Gustav Steinmann Medal (Geologische Vereinigung), and honorary fellowship (AAPG and European Union of Geophysicists).
     Besides being dedicated to his science, to the formulation of new ideas, to his students and colleagues, Bert's most notable characteristic is his personal warmth which promotes a deep friendship with all his associates. Bert Bally richly deserves SEG's Special Commendation Award.
