The history of pulmonary medicine is replete with famous names and milestone events that changed the face of medical science over centuries. From early empirical observations in ancient civilizations to Egyptian texts describing herbal treatments and surgical interventions, it is clear that humanity has suffered from lung disease since the days when Homo sapiens and its predecessors first walked the earth. What follows is not a comprehensive history, but some thoughts on how shifts in knowledge have shaped pulmonary medicine. 

Hippocrates and other Greek practitioners set guidelines for medical practice. They also defined and described many breathing disorders, not the least of which was phthisis, later known as consumption or pulmonary tuberculosis. They described and treated pleurisy and raised awareness about the potential contagiousness of what would ultimately be recognized as infectious lung diseases centuries before the discovery of germ theory.

After that, another Greek physician, Galen of Pergamon, who practiced in the Roman Empire in the second century CE, shaped the future of medicine for centuries. Although many of his findings rooted in anatomical studies and theoretical iterations of what ultimately became the humoral theory for disease needed to be revised or debunked, Galen was forward-thinking in the ways he tied symptomatology (medical semiology), the anatomical structure of the human body, and the external environment on the course of disease. He was among the first to suggest that air, water, and even emotional disturbances could have an adverse impact on human health and wellness.

New theories of medicine prospered only centuries later, when the Islamic physician Avicenna (Ibn Sina) published his Canon of Medicine and Book of Healing (11^th century). The Renaissance, however, brought about some of the greatest changes and the abandonment of most antiquated Galenic theories regarding lung disorders. Anatomists/physicians such as Vesalius, who described the mechanics of respiration and demonstrated the principles underlying positive-pressure ventilation, and Michael Servetus, among the first to describe the pulmonary circulation (early to mid-16^th century), were instrumental in building new foundations from which future discoveries in pulmonary medicine would be made.

From the 17^th to the 20^th century, new breakthroughs would occur particularly in the realms of microbiology, pharmacology, imaging studies, and physician concerns for public health. The discovery of oxygen and the physiology of respiration, accompanied by widespread adoption of Laennec’s stethoscope revolutionized bedside diagnosis and global thinking about the diagnosis, treatment, and prevention of pulmonary diseases. 

Concomitantly, advances in the diagnosis and management of infectious lung disease, the establishment of links between smoking and disorders such as lung cancer and COPD, and growing attention to occupational lung disease anchored pulmonary medicine as a social discipline.

Today, we have reached a new inflection point in the history of pulmonary medicine. Artificial intelligence is reshaping medical diagnosis and decision-making in ways that we cannot yet fully comprehend. Machine-learning algorithms already outperform traditional methods in image interpretation for lung nodules and interstitial lung disease. AI-assisted pathology and cytology promise laboratory expertise in even the most remote corners of the world. Tools combining large language models with genomic and gene-editing processes are accelerating discovery and assisting in earlier diagnosis and management of genetic disorders. Robotics and robotic-assisted bronchoscopy are penetrating the pulmonary procedures world at almost warp speed, providing higher diagnostic yields for lung cancer and other disorders by enabling better access to hard-to-reach peripheral nodules compared to traditional methods.

In the face of such rapidly changing times, our challenge is in finding ways to both embrace and harness computational power. While debates about the risks versus the advantages of AI in pulmonary medicine are helpful, we should also focus on how technological authority can go hand-in-hand with professional responsibility.
