Fred McFeely Rogers (March 20, 1928 - February 27, 2003) was an American television personality, musician, puppeteer, writer, producer, and Presbyterian minister. Rogers was famous for creating, hosting and composing the theme music for the educational preschool television series Mister Rogers' Neighborhood (1968-2001), which featured his kind-hearted grandfatherly personality, and direct connection to his audiences. Originally trained and ordained as a minister, Rogers was displeased with the way television addressed children at the time, and made an effort to change this when he began to write for and perform on local Pittsburgh-area shows dedicated to youth. Rogers developed his own show on WQED in 1968, and it was distributed nationwide by Eastern Educational Television Network.

Rogers was born in Latrobe, Pennsylvania, 40 miles (65 km) southeast of Pittsburgh, to James and Nancy Rogers; he had one sister, Elaine. Early in life, he spent much of his free time with his maternal grandfather, Fred McFeely, who had an interest in music. He would often sing along as his mother would play the piano, and he himself began playing at five. He obtained a pilot's license while still in high school.  Rogers graduated from Latrobe High School (1946). He studied at Dartmouth College (1946-48), then transferred to Rollins College in Winter Park, Florida, where he earned a B.A. in Music Composition in 1951. Rogers was also a trained general aviation pilot.  At Rollins, he met Sara Joanne Byrd (born c. 1928), an Oakland, Florida, native; they married on June 9, 1952. They had two sons, James (b. 1959) and John (b. 1961). In 1963, Rogers graduated from Pittsburgh Theological Seminary and was ordained a minister in the United Presbyterian Church in the U.S.A.  Rogers had an apartment in New York City and a summer home on Nantucket island in Massachusetts. Rogers was red-green color blind, swam every morning, and neither smoked nor drank. He was a vegetarian on ethical grounds, stating "I don't want to eat anything that has a mother." Despite recurring rumors, he never served in the military.  His office at WQED Pittsburgh famously did not have a desk, only a sofa and armchairs, because Rogers thought a desk was "too much of a barrier".Answer this question using a quote from the following article:
