What US Presidents, besides Barak Obama, during their tenure in office also made a point of speaking at one time or another to the nation's children about the importance of going to college?
I've no reason to think that he spoke to the nation's children about going to college, but I wouldn't be surprised if Eisenhower did so.
The impact of Sputnik and the USA's shock at suddenly finding themselves behind in the space-race caused the Eisnehower administration to invest heavily in science education and generally get behind science/engineering qualifications.
