gyula pál

gyula pál -lrb- 1881 -- september 6 , 1946 -rrb- 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 .
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 .
