Muskie's first language was Polish; he spoke it as his only language until age 4. He began learning English soon after and eventually lost fluency in his mother language. In his youth he was an avid fisherman, hunter, and swimmer. He felt as though his given name was "odd" so he went by Ed throughout his life. Muskie was shy and anxious in his early life but maintained a sizable number of friends. Muskie attended Stephens High School, where he played baseball, participated in the performing arts, and was elected student body president in his senior year. He would go on to graduate in 1932 at the top of his class as valedictorian. A 1931 edition of the school's newspaper noted him with the following: "when you see a head and shoulders towering over you in the halls of Stephen's, you should know that your eyes are feasting on the future President of the United States."
