Built in the fall of 1850 of native stone along with an adjoining store and post office, this home was established by John Frederick Heinatz (1822-91), a settler from Germany. For many years he served as Bagdad's postmaster, a public school trustee, superintendent of Sunday School, banker, and practical advisor to his neighbors. He married Emilie Krohn and had nine children, six boys and three girls, seven of whom lived to adulthood in this home.
