of fourteen, and his daughters did not marry instrument makers. While 

 Lundin was active, the company made several large and notable tele- 

 scopes; later they were called upon for smaller instruments for teaching 

 and amateur purposes. In 1933 the Clark concern was taken over by the 

 Sprague-Hathaway Mfg. Co., of West Somerville, Massachusetts. 121 

 Eight years later the Clark Company announced that the Perkin-Elmer 

 Corporation was to act as consultants in connection with the design and 

 construction of its optical systems. 122 This assistance, however, was not 

 enough, and the demise of Sprague-Hathaway, in 1958, carried with it 

 the dissolution of Alvan Clark & Sons.
