Sylvester Roper built steam carriages and motorcycles during the latter half of the nineteenth century. His vehicles were not considered practical but became popular attractions at circuses and fairs. Roper had a heart attack at age 73 while riding one of his steam motorcycles. His death made front-page news in Boston, where he lived and worked.
