                                Introduced in 1904 by Dutch professor Christiaan Eijkman, the Eijkman test was a pioneering method designed to detect harmful fecal contamination in water supplies. This differential test, which relies on temperature-sensitive bacterial growth, provided a significant advancement over earlier, less specific methods for evaluating water safety.
