The following was sent by Elma (Buehler) Lehmann to her cousin Walter Johnston's son Wesley in 1987. I have added some square-bracketed notations and reformatted the text for easier reading.
Emil William Buehler went to Spaulding Crippled School in Chicago. When he was in Eighth  Grade, the principal made my parents take him out of school because he was too smart and that he could benefit more by being on his own. She said he migh come across something he would like to do.
 So my mother showed him how to do office work and selling in my father's store. [Elma wrote in the information on their father, Bill Buehler, that he had a business "Buehler & Jacobs" at 6022 S Western Avenue in Chicago that made cement bird baths, benches and vases and did landscaping. He lost the business during the Great Depression of the 1930's.]
He got so upset that everyone thought just because he was handicapped that he couldn't do anything. He would show them up. Then one day he went out to look for a job. He came home and told my parents he has a job with Zellner Monument Co. He learned that trade from the bottom up.After Mr. Zellner moved to another state, my brother got a job with Thor Washing Machine Co as a draftsman.
He then took a high school test from the State and passed with flying colors and then entered into college. He then got a job with Johnson Motors in Waukegan, Illinois, and became a senior draftsman and retired from there.
In the meantime, he started his own business called "Buehler Memorials" at 823 W. Rollins Road in Round Lake, Illinois January 9, 1965.
My brother designed the lettering and the Dedication Stone on the Veterans of Foreign Wars Memorial in Round Lake and supervised the erection of the lettering and dedication.
 He was a member of MBNA. He was chosen to desing the Antioch War Memorial which was a local war memorial in Antioch (Illinois) Township's service men.
He then sold his business because of health reasons. He still keeps active. He is in charge at Avon Centre Cemetery in Grayslake taking care of the book work and seeing that the groundskeeper takes care of the ground properly.
He was in his own business for 15 years. His godchild is my Charles Lehmann, my son.
