Gyula Pál (27 June 1881 – 6 September 1946) was a noted Hungarian- Danish mathematician. He is known for his work on Jordan curves both in plane and space, and on the

Kakeya problem In mathematics, a Kakeya set, or Besicovitch set, is a set of points in Euclidean space which contains a unit line segment in every direction. For instance, a disk of radius 1/2 in the Euclidean plane, or a ball of radius 1/2 in three-dimensional ...

. He proved that every locally connected planar continuum with at least two points is the orthogonal projection of a closed Jordan curve of the Euclidean 3-space. He was born as ''Gyula Perl'' but hungaricized his surname to Pál in 1909. Fleeing the post-war chaos of Hungary after World War I he moved to Denmark in 1919, possibly by the invitation of Harald Bohr, where he spent the rest of his life and westernized his name to Julius Pal.
