摘要

Frank Seagrave was born in 1860 into a wealthy family in Providence, Rhode Island. At age 14 he witnessed the 1874 total eclipse of the Moon, and from that day forward he was fascinated by astronomy. Soon he was traveling twice a week to Harvard College Observatory in Cambridge, Massachusetts, a round trip of 100 miles, where the harvard astronomers granted the eager youth access to the library and instruments. As a present for his 16th birthday, his father ordered a world-class refractor from Alvan Clark & Sons in Cambridgeport, Massachusetts, America's most esteemed telescope manufacturers. It cost $2,310.80, which in 2012 terms would be about $50,000. The firm delvered the finished telescope to Providence in 1878.
