It established the first law school and the first educational radio station west of the Mississippi, broadcast the world's first educational television programs, and developed and continues to hold preeminence in educational testing.The University has world renowned research programs in genetics, hydraulics, and speech and hearing, and has recorded major innovations in agricultural medicine, biocatalysis, biomedical engineering, biomedical sciences, and pharmacology education. Its graduate programs in audiology, printmaking, creative writing, speech-language pathology, and nursing service administration are first-ranked. Iowa scientists, including James Van Allen, have been pioneers in space research, designing and building research instruments for more than 50 successful U.S. satellites and space probes. The University of Iowa operates one of the nation's most advanced and comprehensive university-owned teaching hospitals. It also has developed the most technically advanced driving simulator in the world.
