 The Harvard Mark I as it appeared on display in the Science Center in the fall of 2019.  
 In July, 2021, the Mark I was moved across the Charles River to a new home with  
Harvard's John A. Paulson School of Engineering & Applied Science, as part of the  
new [Science and Engineering Complex (SEC)](https://seas.harvard.edu/about-us/visit-us/allston/science-engineering-complex) at 150 Western Avenue in Allston, MA.  
The SEC can be reached via a [regular shuttle service between campuses](https://seas.harvard.edu/about-us/visit-us/allston/transportation/shuttle-van-service).



 

  
   
Assistant Professor Marc Aidinoff explains the history of the Mark I computer and how it changed the way that Harvard thinks about science.
