In this chapter of the virtual exhibition “Ludwig Leichhardt: A German Explorer’s Letters Home from Australia,” cultural studies researcher Heike Hartmann presents the deeds, fate, and legacy of Dr. Leichhardt’s companion John Gilbert.

In this chapter of their virtual exhibition “‘Commanding, Sovereign Stream’: The Neva and the Viennese Danube in the History of Imperial Metropolitan Centers,” the authors describe fish resources in St. Petersburg and Vienna and their role in urban life from different perspectives. Fisheries constituted an important part of local economic activities and fishers—both poor professionals and wealthy leisure anglers—were very visible in the cities’ crowds, at their markets, and on the banks of their rivers and canals.

This exhibition tells the story of Mabel “MB” Williams, an extraordinary, ordinary woman who became devoted to national parks and engendered that devotion in others. Historian Alan MacEachern documents her role in shaping the philosophy of Canada’s Dominion Parks Branch (the precursor to Parks Canada) in the early- to mid-twentieth century. Digitized photographs and letters from Williams’s life, her guidebooks and other publications, and audio interviews with Williams herself reveal her influence on, and love for, Canada’s national parks.
