Versuchsleiter

Versuchsleiter is a German noun meaning the person responsible for conducting or supervising an experiment or trial. The term is used in scientific, industrial, and clinical contexts to designate the individual who leads the work, plans the procedure, and oversees its execution.

Role and responsibilities are typically centered on planning and design of the experiment, selecting methods and materials, and ensuring adherence to the established protocol. The Versuchsleiter supervises the personnel involved, monitors safety and compliance with ethical and methodological standards, maintains documentation and data quality, and is often responsible for the interpretation and reporting of results. In many settings, the Versuchsleiter also signs off on the final results and coordinates with supervisory bodies or sponsors.

Contexts and usage vary. In university and research institute laboratories, the Versuchsleiter is akin to a supervisor or lead investigator for a given experiment or project. In the pharmaceutical and industrial testing sectors, the term may designate the study or trial leader responsible for at-site operations. In clinical research, the role resembles that of a principal investigator or site investigator, with duties related to patient safety, protocol adherence, and regulatory compliance; however, terminology differs by organization and country.

Etymology and form. The word combines Versuch (“experiment” or “trial”) with Leiter (“leader” or “director”). The masculine form is Versuchsleiter; the feminine form is Versuchsleiterin. Depending on context, other terms such as Versuchleiter, Versuchsverantwortlicher, or equivalents may be used.

Notes. Versuchsleiter is not a universally fixed formal title; its exact meaning and responsibilities depend on institutional rules, jurisdiction, and the specific field of work.
