JACOB C. H. VOELCKER was born in Louisville, February 13, 1868, and is the
son of Jacob and Louisa (Baab) Voecker, natives of Germany.  The former
came to the Unites States in 1853, and to Louisville, where he became an
industrious and energetic citizen.  The subject received a good practical
education in the public schools of Louisville.  After graduating he
studied pharmacy; clerked for various druggists until the fall of 1887,
when he and L. F. Klooz went into the drug business for themselves.  Under
the firm name of Voelcker & Co., they still carry on the business at No.
800, East Broadway.
