Biography

Constantin Cândea was born on December 15, 1887, in the commune of Mărgineni, Bacău, Bacău County.

He married Maria Cândea née Antoniade on September 27, 1923 (born in Galați – died in Bucharest), a professor of French and Romanian, Doctor of Letters from the Sorbonne, who founded and served as principal of the Girls' Normal School "Queen Marie" (today the National Pedagogical College "Queen Marie") in Ploiești from November 10, 1918.

The couple had two children: Mioara-Rodica Georgescu née Cândea, an architect, (July 9, 1924, Ploiești – September 13, 2017, Montreal), and Ioan-Radu Cândea, a civil engineer (September 24, 1925, Ploiești – February 11, 2016, Bucharest).

Constantin Cândea passed away on March 4, 1971, in Bucharest at the age of 83. He was buried in Bellu Cemetery, Plot 4.

Education In 1906, he graduated from the "Prince Ferdinand" High School in Bacău, His doctoral dissertation, structured in two parts, addressed both fundamental studies in organic chemistry and analyses concerning the economics of energy resources. The first part, entitled "On the Constitution of Diphenol-, Dithiophenol-, Di-α- and β-Naphthol, Dithionaphthol, Dimethylaniline-, Thionaphthenquinones, α-Naphtholisatin and Their Dye Derivatives", examined the structure and properties of a series of phenolic compounds and their derivatives relevant to dye chemistry. The second part, "The Importance of Petroleum for Romanian Industry", analyzed the strategic role of petroleum in the economic development of Romania during the first half of the twentieth century.

Career and Professional Activity At the beginning of his academic career, Constantin Cândea served as a lecturer at the Faculty of Sciences of the University of Bucharest, the institution where he also earned his doctorate in chemistry. At the same time, he was active as president of the Industrial Studies Circle, where he delivered lectures on policies for the development of Romanian industry.

During the first academic year of the Polytechnic School of Timișoara, established following Royal Decree No. 4822 of November 11, 1920, issued by King Ferdinand I, Professor Constantin Cândea founded the chemistry laboratory, while Professor Constantin Stăncescu established the physics laboratory.

As part of his work at the Polytechnic School of Timișoara, during the 1922–1923 academic year, Constantin Cândea also established and directed an official Laboratory for Industrial Research, Studies and Analyses, separate from the teaching laboratories. The laboratory was intended to conduct applied research, technical-scientific studies, and chemical and chemical-engineering analyses for industry.

Organized into several industrial sections (inorganic industry, metallurgy, organic industry, fuels, and general expertise), the laboratory carried out analyses of industrial raw materials, fuels, oils, fats, metals, water, and chemical products, as well as studies with direct industrial applications. Constantin Cândea served as its director, working alongside specialists such as Er. Toporescu, Cerchez Manughevici, C. Ștefănescu, and other academic and technical staff members.

As part of his teaching activity, Constantin Cândea authored several university textbooks used as study materials at the Polytechnic School of Timișoara.

Throughout his academic career, Constantin Cândea regularly participated in international chemistry congresses, where he annually presented papers on the results of his research in organic and industrial chemistry in The Hague, Liège, Brussels, Prague, Paris, Madrid, Sardinia, Rome, and Nancy.

An important part of his scientific and educational work is today preserved in the collections of the Romanian Academy Library, where it is consulted as a reference source for the history of Romanian chemistry.

As Director of the Institute of Chemistry of the Polytechnic School of Timișoara, Constantin Cândea published numerous specialized studies in Romanian and foreign journals. Among these were "The Upgrading of Romanian Lignites", published in România Petroliferă, no. 393, May 31, 1943, and "The Utilization of Methane Gas", published in the same journal, no. 394, July 5, 1943, both reproduced in full by the publication.

On November 22, 1934, following elections for the leadership of the Polytechnic School of Timișoara, Constantin Cândea was elected President of the Council of Deans.

Beginning in 1942, Professor Constantin Cândea served as Vice-Dean of the Faculty of Mining and Metallurgy of the Polytechnic School of Timișoara, playing an important role in organizing the faculty's academic and administrative activities.

Subsequently, between 1946 and 1947, he served as rector of the Politehnica University of Timișoara—then known as the Polytechnic School of Timișoara. in the Runcu–Scorțeni oil field area of Prahova County.

The explosion occurred during intervention works on the extraction installation and resulted in fatalities, numerous serious injuries, and extensive material damage.

The investigation sought to determine the technical causes of the violent eruption of crude oil and gas, analyze the interventions carried out on the jammed well piston, and assess compliance with technical and safety regulations governing petroleum operations. The inquiry also examined the risks posed by accumulations of flammable gases and the procedures used during pressure-release operations in the well column.

Dr. Eng. Constantin Cândea's participation in this investigation reflected recognition of his scientific and technical expertise in petrochemistry and industrial safety. He was appointed by the Ministry of Labour to identify the causes of the accident, clarify responsibilities, and formulate recommendations aimed at preventing similar accidents in Romania's petroleum-producing regions.
