Caroline, the widow of Edward Ehlers (and daughter of Henry Korthauer, one of the original mill builders), sold the farm and the windmill to the Mount Emblem Cemetery Association for $10,000 in 1925. The association planned to convert the land into a cemetery. Although the windmill and farm buildings were scheduled for demolition, the association instead hired Henry and Franklyn Ehlers, Edward’s sons, to preserve the mill as a museum. They rebuilt the sails, installed new shingles and trim on the exterior, painted the mill, and purposely dismantled some of the inner gearing to better show their use. The sails were turned to an ‘X’ formation, which traditionally means the mill is in “a long rest period”. They also turned the cap to the northeast toward the cemetery’s entrance. A barn, the only other structure that survived demolition, was home to the groundskeeper, but was recently destroyed.
