Midwest Old Settlers and Threshers Association (MOSTA) was founded in 1950. The original
idea to form Midwest Old Threshers Association, a non-profit organization, came from a
discussion between Clark Everts, W.E. (Ted) Detrick, Ray H. Ernst and Herman E. Elgar in
September 1949. The four were returning from the Zehr Threshing Reunion in Pontiac,
Illinois. Considering the many Steam Engines and Separators in Henry County, Iowa, the men
decided there was a great potential to host a Threshing Reunion in Mt. Pleasant, Iowa.
After several winter meetings, the election of a Board of Directors and lengthy discussions
about a Mt. Pleasant event, the Association was chartered on August 21, 1950 and the first
Reunion was held September 20 - 21, 1950. The records show that 15 Steam Engines and 8
Separators were exhibited with an estimated 10,000 people attending the first Reunion.

MOSTA CREED
Knowing from experience that each generation enjoys a clean, wholesome gathering of an
educational and historic nature such as ours, the Association hopes to always keep the
gatherings like this, where we can meet and harvest the golden memories of yesteryear
and pause in our daily tasks each year to visit and relax, always with a thought in doing
so to improve the future harvest of good fellowship and citizenship.
Written by Herman E. Elgar, 1951
