Alex Nalbach is an independent scholar with a Ph.D. in World and European History from the University of Chicago, specializing in the history of global newsgathering in the nineteenth and early twentieth centuries. He is currently completing a World History textbook, Discovering the World: Inquiries into the Global Past, an active-learning resource that encourages comparative and connective investigations into environmental and demographic, political and military, economic and technological, cultural and gendered dimensions of the human past.
