Marie Krogh

Marie Krogh

Marie Krogh was a Danish physician and physiologist noted for pioneering work on diabetes, glucose tolerance, and physiological measurement. She combined clinical practice at Rigshospitalet with experimental research at the University of Copenhagen, collaborating with leading scientists and institutions across Europe. Her investigations into blood glucose kinetics and insulin therapy influenced contemporaries in Germany, France, and United Kingdom and helped shape 20th-century endocrinology.

Early life and education

Marie Krogh was born in Copenhagen and received primary schooling in the capital before enrolling at the University of Copenhagen. During a period when women were entering professional studies, she studied physiology under professors associated with the university’s medical faculty and trained clinically at Rigshospitalet. Her formative academic milieu connected her with contemporaries from institutions such as Karolinska Institutet, Sorbonne University, and the University of Oslo, and exposed her to evolving experimental techniques from laboratories in Berlin, Vienna, and Leipzig. Mentors and colleagues in Copenhagen included figures affiliated with the Danish medical establishment and Scandinavian research networks that interfaced with the broader European scientific community.

Medical career and research

Krogh established a medical practice while securing positions that allowed experimental work on metabolic disorders at the University of Copenhagen’s physiology laboratories. She designed experiments integrating clinical observation with quantitative measurement, adopting instrumentation trends popularized by researchers at Charité – Universitätsmedizin Berlin and the Pasteur Institute. Her career moved between hospital wards, laboratory benches, and conference lectures where she exchanged ideas with delegates from the International Diabetes Federation and national societies such as the Danish Medical Association. She contributed to developing standardized protocols for metabolic studies that paralleled contemporaneous efforts at the Royal Society meetings and symposia in Stockholm and Paris.

Contributions to diabetes and physiology

Krogh is best known for her systematic studies of carbohydrate metabolism and the development of oral and intravenous glucose tests that prefigured modern glucose tolerance testing. She quantified blood glucose changes using chemical assays that were contemporaneous with methods from the Ludwig Maximilian University of Munich and analytical approaches advanced at the Institute of Clinical Pathology and Medical Research. Her work influenced clinicians introducing insulin therapy following discoveries by Frederick Banting and Charles Best and intersected with physiological inquiries by investigators in Copenhagen and Uppsala. Krogh explored renal handling of glucose, vascular responses during metabolic challenges, and the effects of dietetic interventions, aligning with broader studies by researchers associated with Johns Hopkins University and the Karolinska Institutet. Through comparative studies, she addressed diagnostic thresholds later echoed in recommendations by national societies and international panels convened in cities such as London, Berlin, and Rome.

Publications and collaborations

Krogh published in Scandinavian and international journals, contributing experimental papers and clinical reports that cited techniques from laboratories in Leipzig and Heidelberg. She collaborated with researchers linked to the University of Copenhagen physiology department and corresponded with physicians and scientists at University College London, Harvard Medical School, and the Pasteur Institute. Her co-authors included clinicians engaged in early insulin administration trials and physiologists studying endocrine control of metabolism. Krogh presented findings at conferences attended by delegates from the Royal Society of Medicine, the International Congress of Physiology, and national congresses of the Danish Medical Association, helping disseminate methods adopted by laboratories in Vienna, Milan, and Helsinki.

Personal life and legacy

Outside medicine, Krogh participated in professional networks that connected Copenhagen with scientific centers across Europe and supported organizations such as the Danish Red Cross during periods of social need. Her legacy persists in the adoption of standardized metabolic testing procedures and in the clinical pathways for diagnosing and managing diabetes promoted by Scandinavian clinicians. Later historians of medicine and archives at institutions like the University of Copenhagen and Rigshospitalet have noted her role in integrating laboratory science into clinical practice. Commemorative discussions of early endocrinology often place her alongside international contemporaries from Canada, United States, and France who transformed care for metabolic diseases in the early 20th century.
