American Physicist
From an early age, I knew I would become a scientist. It may have been my brother Sam's doing. He interested me in the laws of falling bodies when I was ten and helped my father equip a basement chemistry lab for me when I was fifteen. I became skilled in the synthesis of selenium halides.
