Rev. Lorenzo Lorraine Langstroth (25 December 1810 – October 6, 1895), apiarist, clergyman and teacher, is considered the "Father of American Beekeeping." L. L. Langstroth was born in Philadelphia, Pennsylvania. As a youngster, he took such an extraordinary interest in observing the habits of insects that he was punished for wearing holes in the knees of his pants while learning all he could about ant life. He graduated from Yale University in 1831, and subsequently held a tutorship there in 1834-1835. After this he was pastor of various Congregational churches in Massachusetts, including the South Congregational Church in Andover, Massachusetts in May 1836. From 1843-1848 he served as pastor of Second Congregational Church in Greenfield, Massachusetts. A large granite marker was placed on the church's front lawn by national beekeeper E.F. Phillips and others in 1948. In 1848, Langstroth became principal of a young ladies' school in Greenfield, MA. He took up beekeeping in part to distract himself from severe bouts of depression. He married Anne Tucker (1812—23 January 1873) of Massachusetts. They had three children, all born in Massachusetts: James (1837), Anna (1841) and Harriet A. (1847). The Leaf Hive, invented in Switzerland in 1789 by François Huber, was a fully movable frame hive, but had solid frames that were touching and made up the "box". The combs in this hive were examined like pages in a book. Langstroth acknowledged Huber's contribution: "The use of the Huber hive had satisfied me that, with proper precautions, the combs might be removed without enraging the bees, and that these insects were capable of being tamed to a surprising degree. Without knowledge of these facts, I should have regarded a hive permitting the removal of the combs as quite too dangerous for practical use." (''Langstroth on the Honey-Bee'', 1860) Langstroth was popularly credited with discovering the "bee space," though this discovery had already been implemented in European hives. In Europe, both Jan Dzierżon and August von Berlepsch had been focused on side-opened hives. Land resources in Europe had been limited, and traditionally bees were kept in beehouses. The presently so-called “bee space” had been incorporated by Berlepsch following Dzierzon’s discoveries, from the years 1835-1848, into his frame arrangement (Bienen-Zeitung, May 1852). Langstroth made many other discoveries in beekeeping and contributed greatly to the industrialization of modern beekeeping. Langstroth revolutionized the beekeeping industry by using bee space in his top-opening hive. In the summer of 1851 he found that, by leaving an even, approximately bee-sized space between the top of the frames holding the honeycomb and the flat coverboard above, he was able quite easily to remove the coverboard, which was normally well cemented to the frames with propolis, making separation hard to achieve. He later used this discovery to make the frames themselves easily removable. If a small space was left (less than 1/4 inch or 6.4 mm) the bees filled it with propolis; on the other hand, when a larger space was left (more than 3/8 inch or 9.5 mm) the bees filled it with comb. On 5 October 1852, Langstroth received a patent on the first movable frame beehive in America. A Philadelphia cabinetmaker, Henry Bourquin, a fellow bee enthusiast, made Langstroth's first hives for him and by 1852 Langstroth had more than a hundred of these hives and began selling them where he could. Langstroth spent many years attempting to defend his patent without success. He never earned any royalties because the patent was easily and widely infringed. Langstroth hives are still in common use today. He wrote that "... the chief peculiarity in my hive was the facility with which they could be removed without enraging the bees .... I could dispense with natural swarming, and yet multiply colonies with greater rapidity and certainty than by the common methods .... feeble colonies could be strengthened, and those which had lost their queen furnished with the means of obtaining another. .... If I suspected that anything was wrong with a hive, I could quickly ascertain its true condition and apply the proper remedies." Langstroth also found that several communicating hive boxes can be stacked one above another and that the queen can be confined to the lowest, or brood, chamber, by means of a queen excluder. In this way, the upper chambers can be reached only by the workers and therefore contain only honey-comb. This made hive inspection and many other management practices possible and turned the art of beekeeping into a full-scale industry. At the time of Langstroth's contributions, honey was the chief sweetener in American diets, so Langstroth's new beekeeping techniques were of great importance. His discoveries and inventions allowed beekeeping to be done more cost-effectively on a large scale. Since four to twelve pounds of honey, and many hours of bee time, are consumed by bees in the production of one pound of beeswax, honey production was increased from reuse of the comb. Also, being able to remove surplus honey without having to kill the bees meant that many more bees were available the following spring to gather nectar to make honey. In 1853, Langstroth had moved back to Greenfield,MA from Philadelphia and published ''The Hive and the Honey-Bee'' (Northampton (Massachusetts): Hopkins, Bridgman, 1853), which provided practical advice on bee management and, after more than 40 editions, is still in print today. ''Langstroth on the Honey Bee'' was published in 1860. After 1858 Langstroth made Oxford, Ohio, his residence, and devoted his time to beekeeping. The site was and was an ideal place to keep bees. Langstroth planted a row of linden trees along the street and apple trees throughout his property. He sowed buckwheat and clover seed, using of ground for a formal garden, filled with the flowers that bees like best, calling it his honey garden. The home where he lived from 1858 to 1887 was built in 1856 and is now called Langstroth Cottage; it is designated a National Historic Landmark. It was donated to Western College for Women and is today home to the Miami University Center for the Enhancement of Learning and Teaching. Langstroth received his first Italian bees at his home in 1863; Italian bees were more productive than the European bees that were most common in America at the time. He and his son sold Italian queens at 20 dollars each and in one year sold 100 of them, many being sent by post all over the United States. In 1887, he moved with his daughter, Mrs. H. C. Cowan, and her family to Dayton, Ohio. Langstroth died in the pulpit of the Wayne Avenue Presbyterian Church in Dayton, just as he was beginning a sermon on the love of God. He is buried at Woodland Cemetery, Dayton, Ohio. His epitaph reads as follows: The 1885-1895 papers of Lorenzo L. Langstroth are located at the American Philosophical Society Library in Philadelphia. ==Patents== *( USPatent|9300 )—L.L.
