What it is, and who actually made it
The attribution is a small comedy of errors worth getting right. In a 1954 address, President Dwight Eisenhower quoted a former college president: “I have two kinds of problems, the urgent and the important. The urgent are not important, and the important are never urgent.” Eisenhower supplied the aphorism, second-hand and by his own account. The grid built on it belongs to Stephen Covey, whose four quadrants in The 7 Habits of Highly Effective People (1989) and First Things First (1994) turned the line into the tool everyone now draws: urgency across one axis, importance down the other, four boxes, four verbs. Do, schedule, delegate, delete.
