Series IV: Laboratory Account Ledgers, 1900 - 1941

The fourth series, Bio Lab Account Ledgers consists of 4 boxes of ledgers with detailed handwritten entries of students’ information, finances and sundry items. These ledgers provide an overall depiction of life during the beginning of the twentieth century in Cold Spring Harbor. Documents found in this collection reflect the interaction and interrelationship of this Biological Laboratory with the Village and citizens of Laurel Hollow, the Brooklyn Institute of Arts and Sciences and the neighboring institution the Carnegie Institute of Washington Station for Experimental Evolution.
