<p>Not many schools are good in all three of those majors. If you are flexible between Business and Econ and between History and Political Science, things open up significantly. </p>
<p>As it stands, here are schools that are tops in Business, Engineering and History. </p>
<p>Carnegie Mellon University
Cornell University
Johns Hopkins University (I hear they are opening a Business school)
Massachusetts Institute of Technology (Political Science rather than History)
Northwestern University (they now have a Business program)
University of California-Berkeley
University of Michigan-Ann Arbor
University of Notre Dame
University of Pennsylvania
University of Southern California
University of Texas-Austin
University of Virginia
University of Wisconsin-Madison</p>
<p>Like I said, if you are open to Econ as opposed to Business, things open up significantly.</p>
