The École Municipale de Physique et de Chimie Industrielle (EMPCI), later ESPCI, was deeply shaped by the ideas of the Alsatian network, comprising these five scientists. The school adopted the pragmatic German model championed by the Alsatian network, emphasizing practical and experimental training. The EMPCI curriculum allocated only a quarter of its time to theoretical courses, with the rest dedicated to industrially relevant activities: laboratory work, technical drawing, and technological problem-solving, with minimal lectures. Third-year students were introduced to industrial accounting, basic political economy, and discussions on manufacturing processes and industry needs. This reflected a strong commitment to industrial integration. The institution maintained close ties with industry. Industrialists comprised nearly one-sixth of the board, ensuring alignment with industrial strategies by assigning some courses to scientists employed in industry. Faculty members also engaged directly in industrial projects: Schützenberger contributed to chemical manufacturing, particularly fertilizers and synthetic dyes; Lauth collaborated with the Saint-Denis chemical company’s research and production teams; and Haller consulted extensively with Parisian industrialists. The student profile further reinforced the school’s industrial focus. Admission targeted graduates of advanced primary schools, equipped with practical skills in science and mathematics and inclined toward industrial careers, unlike lycée students, who showed little interest in technical fields, or those from basic primary schools, whose education was insufficient. ==== Neglect of scientific research ==== Despite the Alsatian network’s influence, the EMPCI diverged from Lauth’s original vision. Lauth criticized Parisian laboratories as inadequate for students seeking to learn, lacking proper guidance to translate scientific discoveries into practical outcomes or spark new industries. His proposed third-year curriculum aimed to train students in solving industrial problems while keeping them updated on scientific and industrial advancements. However, the EMPCI’s early curriculum prioritized technology over pure science, omitting the latest scientific developments, particularly in the third year, which focused on industrial accounting and economic discussions. Research, even applied, was absent from the curriculum, with no time allocated for it. Regulations discouraged personal research by preparators, requiring them to dedicate their time to supervising students in laboratories, where third-year students spent most of their day. Despite this, exceptions were made, notably allowing Pierre Curie to research piezoelectricity. ==== Balancing Science and Industry ==== The early directors sought to balance the school’s industrial mission with scientific research, though this was challenging. On November 5, 1906, Haller proposed hosting foreign researchers to enhance the school’s reputation, citing the international renown of its faculty. Lauth, then a board member, opposed this, arguing that the school’s industrial focus should not shift toward pure science, as hosting foreign researchers could compromise its purpose. Schützenberger also championed fundamental research. Paul Langevin noted that without Schützenberger’s and his successors’ support, Pierre Curie might not have completed his groundbreaking thesis on magnetism or discovered radium, potentially leaving the school. A 1903 evaluation of Curie acknowledged his tendency toward pure science but valued his contributions to the school’s prestige. This balancing act enabled high-level research, notably by Pierre and Marie Curie, but resources were limited. Terry Shinn notes that Pierre Curie, a mere lecturer, conducted his research in a dilapidated shed with outdated equipment. === From 1930: Embracing research === It was not until the early 1930s, under the leadership of Paul Langevin, that ESPCI began to fully embrace fundamental research and pure science. ==== Nature of the changes ==== Terry Shinn identifies four key changes to the curriculum: a) applied mathematics courses were replaced by advanced theoretical mathematics; b) technological training was partially overshadowed by theoretical sciences and the interplay between theory and experimental discoveries; c) specialized studies supplanted multidisciplinarity; and d) research became an integral part of the curriculum. The proportion of practical training decreased from 74% to 65% of study time, while theoretical instruction expanded. Concurrently, fundamental research gained prominence, exemplified by René Lucas’s work on birefringence and Georges Champetier’s contributions to molecular chemistry. ESPCI became a hub for discussing and refining bold concepts from Louis de Broglie and showcasing discoveries by Frédéric Joliot-Curie. Between 1953 and 1970, the number of active researchers at ESPCI grew from 37 to 116. A 1971 report emphasized that “research is inseparable from true higher education. How can one teach the science being created without participating in its creation?” In 1937, ESPCI relaxed its earlier restrictions, allowing foreign researchers from Luxembourg and Czechoslovakia, limited to 10% of the French student body. Meanwhile, industrial influence waned, with industrialists’ representation on the board halving to 10% between 1950 and 1965. ==== Continued industrial connection ==== The integration of research training, occupying 8% of the curriculum per Shinn’s analysis, and the emphasis on fundamental research marked a return to the principles of the Alsatian network. Yet, ESPCI retained its industrial mission. Industrialists, though fewer, remained on the board, and practical, application-oriented training continued to dominate the curriculum. Even the most fundamental research maintained a focus on practical applications, following the example of the Curies and Langevin, who applied his theoretical work on ultrasonics to invent sonar during World War I. Langevin and his successors rejected any strict divide between pure and applied science. Langevin argued that scientists must connect with society’s needs through engineers and technicians, stating: “The scientist can no longer remain isolated but must be linked to the farmer and the worker, increasingly educated, through a continuous chain of intermediaries and interpreters represented by engineers and technicians at various levels of expertise and roles. The need has become clear to ensure this connection by creating institutions to train individuals not only informed about established science but, above all, immersed in its methods, understanding through direct and sustained experimentation and rigorous laboratory training how science is created, its provisional and living nature, and the degree of confidence its results warrant, too often taught dogmatically, definitively, and lifelessly.” This ethos was deepened by successors like Pierre-Gilles de Gennes.
