Victor Szebehely

Victor G. Szebehely (August 21, 1921 – September 13, 1997) was a key figure in the development and success of the Apollo program.

In 1956, a dimensionless number used in time-dependent unsteady flows was named "Szebehely's number," (In the September and October 1977 issues of the journal Celestial Mechanics, volume 16, an equation used to determine the gravitational potential of the Earth, planets, satellites, and galaxies was named "Szebehely's equation").

His father was an engineer and he started to study in that field, but switched later to physics.

Szebehely authored "Hydrodynamics of Slamming Ships" as David Taylor Model Basin Report 823 in 1952 and co-authored "Ship Slamming in Head Seas" as DTMB Report 913 in 1955.

In 1978 he received the very first Dirk Brouwer Award from the Dynamical Astronomy Division of the American Astronomical Society.
