The essay tracks the reification of actions into entities through notation, pedagogy, and disciplinary conflict: early operational calculus and the symbolic D; the 19th-century rise of matrices and linear transformations; debates between quaternionists and vector analysts; engineers’ pragmatic operator methods (notably Heaviside) versus demands for rigor; and the early 20th-century consolidation of operator theory inside functional analysis (Fredholm, Hilbert, Riesz), culminating in the central role of operators in modern physics and computation.
