Henry  Trimble. 
I  Am.  Jour.  Pharm. 
X  November,  1898. 
entered  the  University  of  Pennsylvania  as  a  special  student  in  chem- 
istry, to  which  branch  of  scientific  study  he  felt  already  strongly 
drawn.  He  continued  here  during  two  years,  working  in  the  analyt- 
ical laboratory  under  the  late  Dr.  F.  A.  Genth,  taking  the  lecture 
courses  in  chemistry,  mineralogy  and  botany,  and  for  the  last  year 
of  his  time  there,  acting  as  lecture  assistant  to  the  writer  of  this 
memoir,  who  then  held  the  chair  of  "  General  and  Organic  Chemis- 
try "  in  the  above-named  institution. 
During  these  years  he  applied  himself  with  great  fidelity  and 
energy  to  the  study  of  the  several  branches  mentioned,  and  in  par- 
ticular, laid  the  foundations  for  that  thorough  acquaintance  with 
analytical  chemistry  that  he  displayed  in  later  years,  when  this 
became  his  special  field  of  work. 
When  in  the  fall  of  1878,  the  writer  was  called  to  the  College  of 
Pharmacy  to  take  the  lectures  of  the  late  Dr.  Robert  Bridges,  then 
the  Professor  of  Chemistry  there,  he  took  Henry  Trimble  as  his  lec- 
ture assistant  there  also.  In  this  same  year,  1878,  he  established 
himself  in  the  retail  drug  business  with  his  friend  and  classmate,  C. 
W.  Warrington,  the  two  taking  the  business  of  their  former  precep- 
tor, S.  Mason  McCollin,  M.D.,  at  Fifth  and  Callowhill  Streets,  in  this 
city.  In  this  business  he  soon  showed  that  he  had  a  practical  side 
to  his  character  and  that  he  could  turn  his  chemical  education  to 
useiul  account.  Not  satisfied  with  the  list  of  preparations  ordinarily 
made  for  sale  by  the  retail  druggist,  he  began  the  manufacture  of 
artificial  fruit  ethers  as  a  specialty,  at  first  on  a  small  scale  and  later 
in  relatively  large  amounts.  It  is  needless  to  say  his  products  were 
unexceptionable  in  quality  and  soon  acquired  a  name  for  themselves 
Meanwhile,  the  chemical  laboratory  of  the  College  of  Pharmacy 
having  also  come  under  the  care  of  Professor  Sadtler  by  reason  of 
the  resignation  of  Dr.  Fred.  B.  Power,  who  had  been  its  director  for 
a  short  time,  Henry  Trimble  was  given  the  active  supervision  of 
this,  and  in  1883,  having  retired  from  active  connection  with  the 
drug  business,  he  was  given  the  full  rank  and  title  of  "  Professor  of 
Analytical  Chemistry  "  in  the  institution. 
From  this  time  on,  all  his  energies  and  efforts  were  given  to  this 
work  and  the  literature  of  pharmacy  and  chemistry  will  bear  witness 
that  all  too  short  as  was  his  term  of  scientific  activity,  he  left  his 
mark  upon  their  pages. 
As  director  of  the  chemical  laboratory,  he  had'to  plan  and  super-
