RUDOLF LEUCKART. 1822-1898. 



CARL GBORG FRIEDRICH RUDOLF LEUCKART was born in the ancient 

 university town of Hehnstedt, on the 7th October, 1822, and died at 

 Leipzig in his 76th year on February 6, 1898. He was elected a

 Professor in Leipzig, where he was soon provided with a new institute
