![]() Peter Henderson |
death Peter Henderson Died 17 Jan 1890 at age 67 (born 9 Jun 1822). Scottish-American horticulturist known as the “Father of American Horticulture.” He learned methods of gardening in the Old World, then immigrated to the U.S. in 1843. He started market gardening in 1847 with a capital of $500.00. The publication Gardening for Profit (1868) was the first American book devoted entirely to market gardening and it encouraged many to enter the business. His seed business was started in 1865. Few men have done more to simplify the handling of plants for commercial use. His greenhouses were models for his many visitors and his methods were widely copied. He also wrote Practical Floriculture (1868) for commercial floriculture, and later, for the amateur audience, Gardening for Pleasure (1875). |

birth Sir Lawrence Bragg Born 31 Mar 1890; died 1 Jul 1971 at age 81. William Lawrence Bragg was an Australian-English physicist and X-ray crystallographer who at the early age of 25, shared the Nobel Prize for Physics in 1915 (with his father, Sir William Bragg). Lawrence Bragg formulated the Bragg law of X-ray diffraction, which is fundamental for the determination of crystal structure: nλ = 2dsinθ which relates the wavelength of x-rays, λ, the angle of incidence on a crystal, θ, and the spacing of crystal planes, d, for x-ray diffraction, where n is an integer (1, 2, 3, etc.). Together, the Braggs worked out the crystal structures of a number of substances. Early in this work, they showed that sodium chloride does not have individual molecules in the solid, but is an array of sodium and chloride ions. |

![]() Grass catcher |
Grass catcher In 1890, black American inventor Daniel Johnson received a patent for "Grass Receivers for Lawn Mowers" (U.S. No. 429,629). This was an improvement on the inventor's own earlier patent application. It consists of a means for suspending the receiver from the mower-handle and enabling the weight of the receiver to be equally distributed. The side of the receiver is covered with woven wire netting. For the purpose of dumping the contents of the receiver, a sliding bottom is provided, operated with a foot stirrup. The patent application was signed by Daniel Johnson making his X mark with two witnesses adding their signatures. |

![]() Micrometer screw guage patent |
Micrometer screw guage patent In 1890, Laroy Sunderland Starrett received a U.S. patent for his micrometer screw guage (No. 433,311), which is the form still familiar and indispensible to any machinist or person measuring small objects in a physics lab. Since 1881, he had worked to improve the micrometers then existing. His design had a vernier scale, a smaller head, a locking device and a small knob extending from the barrel to enable quick rotation while closing the initial gap to the inserted object being measured. By 1899, his micrometer was available in a one-inch size for $6.50, including a leather case. He took out many other patents for the tools he invented or improved, and established a substantial tool manufacturing business. |

birth Elvin Morton Jellinek Born 15 Aug 1890; died 22 Oct 1963 at age 73. Elvin Morton Jellinek was an American physiologist who was a pioneer in the scientific study of the nature and causes of alcoholism and in descriptions of its symptomatology. He was an early proponent of the disease theory of alcoholism, arguing with great persuasiveness that alcoholics should be treated as sick people. Jellinek gathered and summarized his own research and that of others in the important and authoritative works Alcohol Explored (1942) and The Disease Concept of Alcoholism (1960). In the latter book, Jellinek also recognized that some features of the disease (e.g., inability to abstain and loss of control) were shaped by cultural factors. |

![]() Kazimierz Ajdukiewicz |
birth Kazimierz Ajdukiewicz Born 12 Dec 1890; died 12 Apr 1963 at age 72. Polish logician and semanticist who was the chief contributor to the Warsaw school of philosophy and logic, and is credited with developing in 1920 the first deductive theory for the study of logic based on syntax. The dominant theme of Ajdukiewicz's thought was the problem of the dependence of our knowledge and conception of knowledge on language. His main contributions are in the field of logical syntax (with the theory of semantical categories) and in epistemology, with the so-called “radical conventionalism,” a doctrine where he claimed that there exist conceptual apparatuses which are not intertranslatable and that scientific knowledge grows through the replacement of one such conceptual apparatus by another. |
