    Willem de Sitter
    Nacido el
    06 mayo de 1872 ,
    en
    Sneek, Países Bajos,
    Fallecido el
    20 noviembre de 1934,
    en
    Leiden, Países Bajos.
    Willem de Sitter estudió matemáticas y astronomía en Groningen. Paralelamente, entre los años 1897 y 1899, trabajo en el observatorio Cape Observatory en Sudáfrica. Tras doctorarse en 1908, fue nombrado profesor de astronomía de la Universidad de Leyden. A partir de 1919 fue director del observatorio de dicha universidad. De Sitter fue uno de los científicos de la época que contribuyó a popularizar la teoría de la relatividad, participando también activamente en la organización de la expedición de 1919, destinada a verificar experimentalmente una de la predicciones de dicha teoría durante el eclipse que tuvo lugar en este año.
    Cuando Albert Einstein publicó su teoría de la relatividad especial en 1905, pocos astrónomos se interesaron en realizar estudios sobre los posibles efectos que tendría esa teoría sobre la observación. En 1911, de Sitter publicó una teoría simple en la cual asumía la aplicación de la teoría de la relatividad especial de Einstein a los cuerpos astronómicos. En su trabajo, de Sitter concluyó que las estimaciones observacionales realizadas hasta la fecha bajo la teoría newtoniana quedaban obsoletas en función de la relatividad einstiana.
    En de 1913, de Sitter propugnó la observacionalmente comprobada idea de que la velocidad de la luz es independiente a la velocidad de la fuente. Hasta aquel entonces, la teoría sobre la emisión de luz señalaba que la velocidad de ésta dependía de la velocidad de movimiento de la fuente.
