My Beekeeping Experience

Grandpa William and Jim Delaplane, sometime in the 1930s

My grandfather, W. Harvey Delaplane, was a beekeeper in Indiana during the early decades of the twentieth century, as were many folks in those times when it was normal for a rural family to have a cow, chickens, garden, and one or two bee hives. Our family beekeeping enterprise skipped a generation with my father, but Dad was resolved to get me involved so for my 13th birthday he bought me a beginner's beekeeping kit, complete with a hive, veil, gloves, and a certificate for a mail-order package of bees. I accepted the challenge with immediate, and perhaps excessive, enthusiasm. Excessive, my father came to believe, because from that point on I was a lackluster helper around the farm. While Dad would be plowing, planting, cultivating, and harvesting, his teenage son would be busy in the bees, planning for the day when he would be operating a beekeeping empire. One hive grew to two, then to four, then to eight, and ultimately 51 which proved to be almost too much for a kid to handle. It would have been too much indeed were it not for the solid guidance I received from my mentor, Mr. Paul Champ. Mr. Champ was a beekeeper in our neighborhood who operated about 300 hives. He patiently let me "help" him during my earliest years as a beekeeper. It was he who first showed me a queen bee, and it was he who introduced me to the peculiar pleasures of working sleepy bee yards tucked away in remote country places.

It was my indomitable interest in beekeeping that led me to pursue graduate study in entomology. I learned that bee science is only partly similar to bee keeping, but my path led me nevertheless to a post at the University of Georgia that melds duties in apicultural extension, research, and teaching. Now I find myself conveniently straddling the world of the academician and the world of the practicing beekeeper.
