query: What is the significance of David Bates Douglass' design of Mount Hermon Cemetery in 1848?
answer: David Bates Douglass' design of Mount Hermon Cemetery in 1848 was significant because it was modeled after his earlier designs for Green-Wood Cemetery and Albany Rural Cemetery, all of which followed the philosophy of Sir Christopher Wren in creating pastoral cemetery settings away from cities.  This design resulted in Mount Hermon becoming Canada's first garden cemetery and achieving historic landmark status.
