Biography
Alvan Clark fashioned a reputation as a maker of precision refracting telescopes, guiding astronomy from a workshop in Massachusetts where he and his sons ground lenses large enough to serve the nation's premier observatories.
His instruments helped astronomers chart planets and stars, and his burial at Mount Auburn celebrates a life devoted to craftsmanship that widened humanity's view of the heavens.
