ROSENGARTEN  &  SONS. 
By  William  McIntyre. 
The  manufacturing  business  of  the  firm  of  Rosengarten  &  Sons 
was  established  in  1822.  The  original  partners  were  Seitler  and 
Zeitler;  the  former  a  Swiss  from  one  of  the  French  Cantons,  the 
latter  a  German  from  Wurzburg. 
George  D.  Rosengarten  was  at  that  time  engaged  in  the  wool 
business,  and  being  a  competent  accountant,  and  having  the  confi- 
dence of  this  chemical  firm,  was  engaged  to  settle  the  accounts. 
Being  conversant  with  the  French  language  as  well  as  his  native 
German,  he  was  able  to  do  this  to  their  evident  satisfaction. 
On  December  1,  1823,  ne  became  a  partner  of  Carl  Zeitler  under 
the  firm  name  of  Zeitler  &  Rosengarten.  From  this  time  on  nearly 
all  the  books  of  this  firm  and  its  various  successors  are  still  in  a 
state  of  preservation,  and  the  history  can  be  followed  with  some 
exactness. 
Quinine  Sulphate,  Sulphuric  Ether,  Spirit  of  Nitre,  Aqua  Am- 
moniac, Acetic  Ether  and  Hoffman's  anodyne  were  made  at  this  time. 
The  first  sale  of  Quinine  by  the  firm  of  Zeitler  &  Rosengarten  was 
made  in  December,  1 823. 
On  October  13,  1824,  Carl  Zeitler  withdrew,  and  the  receipt 
showing  that  his  interest  was  bought  by  Geo.  D.  Rosengarten  still 
exists.  From  this  time  the  business  gradually  increased,  and  later 
his  cousins,  Samuel  and  Hermann  Rosengarten  were  employed. 
In  1832  Morphine  Sulphate  and  Acetate  were  manufactured,  the 
opium  being  bought  from  the  local  wholesale  druggists.
