In 1955 David acquired Pinehurst Farm which had been in the family since 1910. David had a keen interest in breeding registered Holsteins and developing bloodlines to produce exceptional dairy cows. He went on to breed and develop a Holstein herd known worldwide. In 1976 and 1980 Pinehurst Farm won Premier Breeder and Premier Exhibitor at all three National Holstein shows, a feat achieved only by Pinehurst. In 1975, 1976, 1977, 1978, 1979, 1980 and 1981 the Pinehurst herd was the leading exhibitor of All-American Nominees. David managed and worked dairy cattle sales across the country and exported thousands of cattle to Japan and Europe.
David was preceded in death by his parents, brother Peter Bachmann, sister Mary Jannone, sister Joan Ribich, and daughter Mary Joan Bachmann.
David is survived by his wife Diane, their son David Bachmann, Jr., his former daughter-in-law Brenda Blum; David, Jr. and Brenda’s children, Christopher Bachmann, Matthew (Lauren) Bachmann and Alexandra Bachmann; Matthew and Lauren’s children Eleanor and Evander.
