My mother, Grace Laemmlen, was a school teacher. After she and my dad married in June 1954, they traveled to Hagerstown, Maryland where my dad served for two years as the administrator of the hospital at Brook Lane Farm. As a Mennonite, he was a conscientious objector and this was part of his 2 year voluntary service. My mother found this teaching position nearby in Leitersburg at the Washington School.
Here are some wonderful photos of my mom and her school room and the beautiful children she taught.
My mother had perfect penmanship. 
The Pigley-Wigley Store
I love these three class pictures. They give me a feel for the wiggly children mom taught!
Here are a few newspaper articles that mention mom as a teacher in Leitersburg in 1955/1956:
Here is a look at the Washington School back then:
Today this beautiful school is a well-known haunted house, having been abandoned long ago by school children. How much better to hear happy children’s voices in the hallways, than frightened ones.
I loved growing up with a mom who was a school teacher. She taught me to read before I went to Kindergarten. When I was older I loved helping her set up her classroom every year before school started. She taught 3rd grade for years in Orange Cove, California at the Sheridan Elementary School. Then for several years she supervised student teachers for Pacific College in Fresno. She was a wonderful teacher and a mentor for teachers.
Those pictures are priceless!
