Robert Jacobus Forbes or Robert James Forbes (21 April 1900, Breda – 13 January 1973, Haarlem) was a Dutch chemist and historian of science and professor in the history of applied science and technology at the University of Amsterdam. He was the recipient of the first Leonardo da Vinci Medal, the highest award by the Society for the History of Technology (SHOT).

Biography Family, youth and education Forbes was born in Breda as son of William Forbes, a military engineer and later administrator at the Bataafse Petroleum Maatschappij, and Maria Sara Johanna (van Houten) Forbes. The Forbes family was of Scottish origin and a descendant of the Scottish theologian John Forbes of Corse. He spent much of his childhood in China, where he attended the Public School of the International Settlement in Shanghai.

Back in the Netherlands from 1912 to 1917 he attended the Hogere Burgerschool (HBS) in Leiden. From 1917 to 1923 he studied chemical technology at the Delft University of Technology, where he obtained his engineering degree.

Career From 1923 to 1958 Forbes worked for Royal Dutch Shell. The first two years he worked as chemist at the Shell Technology Centre Amsterdam. From 1925 to 1931 he worked in the Dutch East Indies as engineer at oil-refinery at Balikpapan, Borneo. After his return to the Netherlands in 1931 he did research about the application of asphalt in the construction of roads. In the later years he moved into the development of analytic methods, and participated in the Standardization Committee of the Institute of Petroleum in London. In his last three years from 1952 to 1955 he managed the scientific publication department, and wrote about the history of the Royal Dutch Shell.

In 1947 Forbes had also been appointed professor in the history of applied science and technology at the University of Amsterdam. After his retirement from Shell in 1958 he was secretary of the Koninklijke Hollandsche Maatschappij der Wetenschappen in Haarlem as successor of the late Johannes Abraham Bierens de Haan. In 1960 he was appointed professor in the history of physics and chemistry at the University of Amsterdam.

Forbes retired from the University of Amsterdam on 1 September 1967."Prof. dr. ir. RJ Forbes, 1900 - 1973," at albumacademicum.uva.nl. Accessed 2017-09-09. He died at his home at Haarlem 13 January 1971 at the age of 72.

Recognition In 1953 Forbes was awarded an Honorary degree by the Technion – Israel Institute of Technology. He was appointed member of the Royal Netherlands Academy of Arts and Sciences in 1959. The Newcomen Society awarded him the Dickinson Memorial Medal in 1960, and elected him Honorary President. In 1962 Forbes was awarded the first Leonardo da Vinci Medal by the Society for the History of Technology (SHOT).

Work As science historian Forbes wrote about the history of technology, particularly oil technology in the ancient world. In the 1930s he had studied the use of bitumen, asphalt, petroleum and building of roads in the Ancient world. Subsequently he had studied metals and mining from 1935 to 1950, and in between also ancient irrigation and water resource management in the years 1938 to 1941.

Forbes also wrote a book about Simon Stevin, describing Stevin's mill building and hydraulic engineering work. His work A history of science and technology, written with Eduard Dijksterhuis, proposed a synthesis of the history of science. In total Forbes published over thirty books and about two hundred articles.

History of ancient roads and their construction In his youth Forbes had developed an interest in archaeology, which became of interest when he started to study the application of asphalt in the construction of roads at Shell in 1931. Under guidance of the Dutch archaeologist and orientalist Henri Frankfort, Forbes went to Iraq to collect samples of ancient mastic, which he analyzed in the Shell laboratory. This research first let to the 1934 publication of Notes on the history of ancient roads and their construction.Forbes, R.J. Notes on the History of Ancient Roads and Their Construction. Amsterdam: Uitgeversmij, 1934. Print, ; 2nd ed., Amsterdam: Adolf M. Hakkert, 1964. .

Stevens in The Classical Review 49, #2 (May 1935), p. 87, .Reviewed by I. A. Richmond in The Journal of Roman Studies 25 (1935), pp. 113-114, .

In 1936 Forbes also published Bitumen and petroleum in antiquity."Forbes, Robert James. Bitumen and petroleum in antiquity. Reviewed by K. C. Bailey," in: The Classical Review, 50, #6 (December 1936), p. 243, . In this work Forbes summarize the use of bitumen and petroleum in antiquity, as Hassan (2013) described, that:

According to Hassan (2013) Forbes had also pointed out, that "by 347 AD the Chinese local oil and gas industry had developed considerably, because oil wells up to 800 feet were being drilled using bits connected to bamboo poles."

Cooperation at the University of Amsterdam

At the University of Amsterdam he became befriended with David Cohen (1882–1967), professor of Ancient History, who became his mentor. He became supporter of the Allard Pierson Stichting with its Allard Pierson Museum, the archaeological museum of the University of Amsterdam, and joined the Vooraziatisch-Egyptisch Gezelschap Ex Oriente Lux. Their annual publication gave Forbes a forum to publish his work.

In Shell his historical work became known to its chairman Henri Deterding, who supported the publication of his work. With Deterding Shell supported the Allard Pierson Stichting, which initiated the chair for the history of applied science and technology at the University of Amsterdam in 1946 for Forbes.

Bibliographia Antiqua: Philosophia Naturalis 1940–1963 From 1940 to 1963 Forbes published his first book series, entitled Bibliographia Antiqua: Philosophia Naturalis, in 10 parts with 6 volumes and 2 supplementary volumes in Dutch. The subjects of these works were:
