Theodore Dehone Judah (March 4, 1826 – November 2, 1863) was an American railroad and civil engineer who was a central figure in the original promotion, establishment, and design of the First Transcontinental Railroad. He found investors for what became the Central Pacific Railroad (CPRR).
People thought his idea to build a transcontinental railroad across the US was crazy. So he earned the name 'Crazy Judah'.
