Andrew Meikle was a Scotsman of the late 18th and early 19th century. He is credited for inventing the drum-style threshing machine that could be operated with wind power, horse power, and eventually by steam power.
Andrew Meikle was born in 1719 in Houston Mill in eastern Scotland in the UK. After inheriting his father’s mill, Meikle invented a threshing machine that greatly increased the production efficiency of grain.
Threshers are machines that remove the outer husks from grains such as wheat. Before the threshing machine, separating the grain from the chaff was a labor intensive process. The thresher was a very important development in the huge changes in British agriculture in the late 18thcentury. Meikle’s first two threshers were not successful. But eventually he designed a machine based on a drum in which flax fibers were beaten to separate the husks.
