beniamino bufano was a california-based italian american sculptor, best known for his large-scale monuments representing peace. bufano's sculpture "saint francis of the guns of 1968" stands at san francisco city college in front of the science building. it is a statue of saint francis of assisi—san francisco's namesake—made from melted-down guns mixed with bronze to prevent rust from the city's dampness; this work was inspired by that year's assassinations of martin luther king, jr. and robert f. kennedy. the sculpture is of a 9-ft tall figure of a robed catholic saint, his arms spread in peaceful greeting. on his robe, bufano created a mosaic tile mural showing the glowing heads of four of america's assassinated leaders: abraham lincoln, martin luther king jr., robert kennedy and john f. kennedy. this was one of bufano's last works before he died.
