Powers-Weightman-Rosengarten  Co.  Round  Out  a  Century  of 
Commercial  Activity. — This  well-known  firm  of  chemical  manufac- 
turers have  made  a  modest  announcement,  in  the  usual  Philadelphia 
conservative  style,  that  "  the  firm  has  completed  one  hundred  years 
of  continuous  activity  in  the  chemical  industry  in  America." 
This  consolidation  of  two  of  Philadelphia's  noted  chemical  manu- 
facturing firms  traces  back  its  commercial  history  to  those  early 
pioneers  in  the  manufacture  of  medicinal  chemicals  George  D.  Rosen- 
garten,  Charles  Zeitler  and  John  Farr.  During  the  century,  the 
further  efforts  of  Thos.  H.  Powers,  William  Weightman  and  the 
Rosengartens  have  marked  a  continuous  development  of  one  of  the 
city's  greatest  industries.  The  awards  of  medals  made  to  both 
Powers  &  Weightman  and  Rosengarten  &  Sons  at  numerous  exhibi- 
tions and  by  scientific  bodies  have  been  well-earned  testimonies  to 
the  quality  of  their  productions  and  the  integrity  of  their  business 
management. 
The  American  Journal  of  Pharmacy  is  pleased  to  extend  to 
Messrs.  Powers-Weightman-Rosengarten  Co.  on  this  occasion  our 
sincere  felicitations  and  congratulations  accompanied  by  hearty  best 
wishes  for  continued  prosperity  and  the  success  that  their  efforts 
merit.
