GALVESTON, Texas -- Lynn Alperin poses for a photo with a copy of her book, "Custodians of the Coast," at her home, April 7. The retired medical writer recently gifted the U.S. Army Corps of Engineers (USACE) Galveston District’s historical archives a signed copy of her book after learning there weren’t any copies left in its libraries. For a long time, Alperin’s book was considered required reading for incoming district commanders. Photo by Carlos Gomez
