Records of the Harvard College Observatory Chronometric Expedition
FOUND IN:
Harvard University Archives
Collection Identifier: UAV 630.349
Overview:
In the mid-nineteenth century, the Chronometric Expedition was carried out by the Harvard College Observatory, under the direction of William Cranch Bond and in conjunction with the United States Coast Survey. The expedition used chronometers that were made by William Bond & Son, the Bond family's private business, to determine differences of longitude between the observatories in Cambridge, Massachusetts and Liverpool, England. The records primarily consist of notebooks, data sheets,...

Records of the Harvard College Observatory Time Service
FOUND IN:
Harvard University Archives
Sub-Fonds Identifier: UAV 630.377
Overview:
In 1872, under Director Joseph Winlock, the Harvard College Observatory established the world’s first public time service, which it provided as a commercial service until 1892. The Observatory sold its time service to railroads and businesses by sending hourly signals over Boston’s fire alarm system and distributing time across the region via Western Union telegraph lines; this work eventually resulted in the establishment of the country's first time zone. The Records of the Harvard College...
