I forgot that I had this picture and article about Mouse (Move Only Under Spring Energy) competition that my daughter, Ife (smiling in the middle of photo 1) participated in as a middle school student. Unfortunately I can’t put my hands on a photo of her contraption but you can see one of them created by Mr. Bigford.
Mrs. Emma Davis Topp roomed with Moses and Jean Walker, after her husband died in 1912. Her husband, John W. Topp was twenty years older than she was. He was an engineer, a black Canadian who arrived in Detroit at age 17 in 1875. My grandparents, Mershell and Fannie Graham were also roomers after their marriage in 1919. Mrs. Topp was born in Mississippi and attended school through the 8th grade. She was working as a dressmaker in 1920. By 1930 she had moved to Los Angeles, CA and was living with her cousin and aunt. She was no longer working and lived the with her cousin until she died in 1948.
