Kodak introduces their first Brownie, a very inexpensive user-reloadable point-and-shoot box camera.
H. de Vries, C. Correns, and E. Tschermak independently rediscover Mendel's paper. Using several plant species, de Vries and Correns had performed breeding experiments that paralleled Mendel's earlier studies and had independently arrived at similar interpretations of their results. Therefore, upon reading Mendel's publication they immediately recognized its significance. W. Bateson also stresses the importance of Mendel's contribution in an address to the Royal Society of London.
K. Landsteiner discovers the blood-agglutination phenomenon in man.
Karl Pearson develops the chi-square test.
Herman Hollerith patents Apperatus For Punching Record Cards
Kodak introduces the 120 film format.
H. de Vries adopts the term MUTATION to describe sudden, spontaneous, drastic alterations in the hereditary material of Oenothera.
T. H. Montgomery studies spermatogenesis in various species of Hemiptera. He concludes that maternal chromosomes only pair with paternal chromosomes during meiosis.
Arthur Korn devises practical telephotography technology (reduction of photographic images to signals that can be transmitted by wire to other locations).Wire-Photos are in wide use in Europe by 1910, and transmitted to other continents by 1922.
Walter Sutton concludes that (a) chromosomes have individuality, (b) that they occur in pairs, with one member of each pair contributed by each parent, and (c) that the paired chromosomes separate from each other during meiosis.
T. Boveri studies sea urchin embryos and finds that in order to develop normally, the organism must have a full set of chromosomes, and from this he concludes that the individual chromosomes must carry different essential hereditary determinants.
William Bateson coins terms that will become essential to describing findings in the new science of heredity: GENETICS, F1, F2, ALLELOMORPH (later shortened to ALLELE), HOMOZYGOTE, HETEROZYGOTE, and EPISTASIS.
The first motor taxis appear in London
The concepts of PHENOTYPE, GENOTYPE, and SELECTION were introduced and clearly defined by Wilhelm Ludwig Johannsen.
The Rolls-Royce company is founded in Britain.

The first motorized buses operate in London.
The first neon signs appear.
K. S. Merezhkovsky suggests that chloroplasts originated as a cyanobacterium swallowed by a protozoan, i.e., algal and plant cells result from two independent organisms that became symbionts. The idea will be largely forgotten until it is suggested again in the 1960s.
Lucien Claude Cuénot performs crosses between mice carrying a gene that gives them yellow fur. Since they always produce yellow furred and agouti offspring in a 2:1 ratio, he concludes they are heterozygous. (In 1910, W. E. Castle and C. C. Little will show that yellow homozygotes die in utero. This dominant allele is thus the first gene shown to behave as a homozygous lethal.)
Computer Pioneer Grace Hopper is Born
William Bateson and Reginald Crundall Punnett report the discovery of two new genetic principles: LINKAGE and GENE INTERACTION.
The Autochrome plate is introduced. It becomes the first commercially successful color photography product.
(no entry for this year)
Kinemacolor, a two-color process known as the first commercial "natural color" system for movies, is introduced.
General Motors Corporation is formed.
The Ford Motor Company produces the first Model T. Ultimately, more than 15 million will be produced.
Godfrey Harold Hardy, a Cambridge mathematician, writes a letter to the editor of Science, suggesting that Mendelian mechanisms acting alone have no effect on allele frequencies. The letter begins, I am reluctant to intrude in a discussion concerning matters of which I have no expert knowledge, and I should have expected the very simple point which I wish to make to have been familiar to biologists. However,... This short (less than one page) letter constitutes Hardy's entire lifetime contribution to the field of biology, yet still forms the mathematical basis for population genetics.
Kodak announces a 35 mm "safety" motion picture film on an acetate base as an alternative to the highly flammable nitrate base. The motion picture industry discontinues its use after 1911 due to technical imperfections.
The plastic age begins with the first commercial manufacture of Bakelite.
A. E. Garrod publishes Inborn Errors of Metabolism, the earliest discussion of the biochemical genetics of man (or any other species).
George H. Shull advocates the use of self-fertilized lines in production of commercial seed corn. The hybrid corn program that resulted, created an abundance of foodstuffs worth billions of dollars.
H. Nilsson Ehle puts forward the multiple-factor hypothesis to explain the quantitative inheritance of seed-coat color in wheat.
W. Johannsen's studies of the inheritance of seed size in self-fertilized lines of beans leads him to realize the necessity of distinguishing between the appearance of an organism and its genetic constitution. He invents the terms PHENOTYOPE and GENOTYPE to serve this purpose, and he also coins the word GENE.
In the early 1990's, Robert Robbins was a faculty member at Johns Hopkins, where he directed the informatics core of GDB — the human gene-mapping database of the international human genome project. To share papers with colleagues around the world, he set up a small paper-sharing section on his personal web page. This small project evolved into The Electronic Scholarly Publishing Project.
In 1995, Robbins became the VP/IT of the Fred Hutchinson Cancer Research Center in Seattle, WA. Soon after arriving in Seattle, Robbins secured funding, through the ELSI component of the US Human Genome Project, to create the original ESP.ORG web site, with the formal goal of providing free, world-wide access to the literature of classical genetics.
Although the methods of molecular biology can seem almost magical to the uninitiated, the original techniques of classical genetics are readily appreciated by one and all: cross individuals that differ in some inherited trait, collect all of the progeny, score their attributes, and propose mechanisms to explain the patterns of inheritance observed.
In reading the early works of classical genetics, one is drawn, almost inexorably, into ever more complex models, until molecular explanations begin to seem both necessary and natural. At that point, the tools for understanding genome research are at hand. Assisting readers reach this point was the original goal of The Electronic Scholarly Publishing Project.
Usage of the site grew rapidly and has remained high. Faculty began to use the site for their assigned readings. Other on-line publishers, ranging from The New York Times to Nature referenced ESP materials in their own publications. Nobel laureates (e.g., Joshua Lederberg) regularly used the site and even wrote to suggest changes and improvements.
When the site began, no journals were making their early content available in digital format. As a result, ESP was obliged to digitize classic literature before it could be made available. For many important papers — such as Mendel's original paper or the first genetic map — ESP had to produce entirely new typeset versions of the works, if they were to be available in a high-quality format.
Early support from the DOE component of the Human Genome Project was critically important for getting the ESP project on a firm foundation. Since that funding ended (nearly 20 years ago), the project has been operated as a purely volunteer effort. Anyone wishing to assist in these efforts should send an email to Robbins.
With the development of methods for adding typeset side notes to PDF files, the ESP project now plans to add annotated versions of some classical papers to its holdings. We also plan to add new reference and pedagogical material. We have already started providing regularly updated, comprehensive bibliographies to the ESP.ORG site.
