Amit Sengupta (1958-2018) believed the job of a doctor was not simply to treat a sick individual, but to build a society in which health is a fundamental right of all citizens. In these times of the Covid-19 pandemic, such a perspective is more relevant than ever. The essays in this book trace how Sengupta's work and politics were integral to the history of the health movement, and how this movement evolved from 'medicines for all' to 'health for all'. Sengupta's work of a lifetime is supplemented and framed by his colleagues in the movement: David Sanders, SP Shukla, Prabir Purkayastha, Satyajit Rath, Sarojini Nadimpally, Indranil, David Legge, Kajal Bharadwaj and many others.
