“South Wind, Clear Dawn,” a woodcut on paper made around 1830 by Japanese artist Katsushika Hokusai, is on display at the Carnegie Museum of Art.

PITTSBURGH — Two rarely seen Japanese collections from the early years of the Carnegie Institute are being displayed through July 21 in Gallery One at the Carnegie Museum of Art.

“Japan Is the Key: Collecting Prints and Ivories, 1900–1920” reveals the story of art collecting and influence by industrialist H.J. Heinz and poet Sadakichi Hartmann.

Works on view include “South Wind, Clear Dawn,” a dramatic image of Mount Fuji by Katsushika Hokusai, and a piece of carved ivory called “Long Procession of Toads,” a single tusk of ivory made into a lively parade of frogs and toads satirizing a Japanese warlord.

Hartmann and Heinz were vastly different men, united by a common fascination with Japan at the turn-of-the-century.

Hartmann was a poet of Japanese-German parentage who seems to have masterminded the Carnegie Institute Department of Fine Arts’ controversial early exhibitions of Japanese prints and avant-garde photography.

Heinz, a pillar of industrial America, visited Japan through his business engagements and his commitment to Christian ministry work, loaning his rapidly growing collection of ivory carvings to Carnegie Institute in 1910.

Both left a legacy in the collections of the Institute, now Carnegie Museums of Art and Natural History, 4400 Forbes Ave.
