Background/Objectives: Franz Tappeiner (1816–1902) is often celebrated as a pioneer of alpine medicine and the founder of Tappeiner Promenade in Meran (South Tyrol, Italy). However, his legacy extends far beyond the scenic infrastructure, encompassing a comprehensive vision of physical activity as a public health intervention. His multidisciplinary practice anticipated the principles of contemporary rehabilitation, preventive medicine, and climate-sensitive public health. Methods: This historical public health analysis, combining biographical, contextual, and material–spatial approaches, reinterprets Tappeiner’s writings, institutional engagements, and civic projects through the lens of modern public health frameworks. Drawing on primary materials (e.g., published articles, autobiographical fragments, and commemorative texts) and recent evidence from rehabilitation and environmental health research, these contributions were contextualized. Results: Tappeiner’s early focus on infectious disease prevention (e.g., cholera and tuberculosis) transitioned into a strategic emphasis on recovery and behavioral therapy through environmental design. The walking therapy model of Max Joseph Oertel, locally realized in the Tappeiner Promenade, prefigured modern concepts such as structured green rehabilitation, walkability, and urban-health citizenship. His systematic integration of graded walking into civic infrastructure represents one of the earliest documented examples of embedding physical activity promotion at the population level. He contributed substantial personal funds to the path’s construction, embedding therapeutic gradients, curating vegetation, and promoting inclusive design to support convalescence. Contemporary research supports the intuition that green, low- to moderate-intensity walking improves cardiometabolic health, psychological well-being, and functional capacity. Moreover, his integrative ethos, merging clinical medicine, civic ethics, and spatial intervention, parallels contemporary eco-social models of public health. Conclusions: Franz Tappeiner’s career exemplifies a still-relevant model of physician leadership that is empirically grounded, socially accountable, and ecologically attuned, with physical activity promotion embedded as a central element of his public health vision. His work invites reflection on how medical professionals can shape not only individual care but also urban environments and collective health futures.
