in terms of gender, race and class, but academies open the world of research up beyond the traditional patronage system. In 1799, Louis-Nicolas Robert patents the paper machine. When he quarrels over invention ownership, he seeks financing from the Fourdrinier brothers. In 19th century Europe, businessmen financed the application of science to industry. In the eighteenth and nineteenth centuries, as the pace of technological progress increased before and during the industrial revolution, most scientific and technological research was carried out by individual inventors using their own funds. A system of patents was developed to allow inventors a period of time (often twenty years) to commercialize their inventions and recoup a profit, although in practice many found this difficult. The Manhattan Project (1942 – 1946) had cost $27 billion and employed 130,000 people, many of them scientists charged with producing the first nuclear weapons. In 1945, 70 scientists signed the Szilard petition, asking President Truman to make a demonstration of the power of the bomb before using it. Most of the signers lost their jobs in military research. In the twentieth century, scientific and technological research became increasingly systematized, as corporations developed, and discovered that continuous investment in research and development could be a key element of success in a competitive strategy. It remained the case, however, that imitation by competitors - circumventing or simply flouting patents, especially those registered abroad - was often just as successful a strategy for companies focused on innovation in matters of organisation and production technique, or even in marketing. Today, many funders move towards transparent and accessible research outcomes through data repositories or Open-access mandates. Some researchers turn to crowdfunding in search of new projects to fund. Private and public foundations, governments, and others stand as an expansion of funding opportunities for researchers. As new funding sources become available, the research community grows and becomes accessible to a wider, and more diverse group of scientists. Methodology to measure science funding The guidelines for R&D data collections are laid down in the Frascati Manual published by the OECD. In the publication, R&D denotes three type of activity: basic research, applied research and experimental development. This definition does not cover innovation but it may feed into the innovative process. Business sector innovation has a dedicated OECD manual. The most frequently used measurement for R&D is Gross domestic expenditure on R&D (GERD). GERD is often represented in GERD-to-GDP
