  thomas jefferson [...] engineered the lousiana purchase, by which for
  $15,000,000, the us acquired [...] lousiana, arkansas, oklahoma, missouri,
  kansas, iowa, nebraska, minnesota, north dakota, south dakota, colorado,
  montana and wyoming. jefferson was curious about this new land. *who* was
