[Our urologic heritage: Leopold Casper (1859-1959)].

It is reminded of the outstanding Berlin urologist Leopold Casper (1859-1959), whose work reflects half a century of the history of Berlin urology. As founder of the ureteral catheterisation and the functional renal diagnostics he helped the urology, for the recognition of which as an undependent subject he fought a life-long struggle, to further reputation.
