All three of the boys attended the University of Kansas at Lawrence.
The Economics department at the University of Chicago at that time was a fairly contentious place. Lloyd was the youngest of three sons of Leroy and Lulu Appleton Metzler, who were both schoolteachers and both had college degrees. Leroy was a Civil engineer, and Donald became the head of the Engineering department and served as mayor of Lawrence.
Lloyd was heading for a degree and career in business until he fell under the tutelage of John Ise who convinced him to switch to Economics and who was a lifelong hero.
Metzler worked post-World World War II with the Office of Strategic Services (Office of Strategic Services) in Washington District of Columbia, and spent much of that time working on post war reconstruction in Europe. Metzler was awarded a Guggenheim Fellowship in 1942 upon completing his Doctor of Philosophy at Harvard.
He was made a Distinguished Fellow of the American Economic Association in 1968. In the early 1950s Metzler"s career was severely impacted by the discovery of a brain tumor, and several surgeries.
He continued to teach for another 20 years at the University of Chicago.

Although most of his career was spent at the University of Chicago, he was not a member of the Chicago school, but rather a Keynesian.
