The OHS 2017 Calendar celebrates the 62nd Annual OHS Convention—Minnesota, August 5–11, 2017—highlighting organs in our nation’s heartland. This calendar is filled with gorgeous photographs by Len Levasseur—12 different instruments, one for each month—ranging from a grand 1877 Johnson & Son to a still modern-looking 1963 Casavant, with instruments by 19th century Minnesota builders Joseph Lorenz and Vogelpohl & Spaeth, the magnificent pair of Skinner and Aeolian-Skinner/Quimby organs at the Cathedral of Saint Paul, plus unusual examples by Steer & Turner, Hinners, and Hutchings, more contemporary classics by Schlicker, Wicks, and C.B. Fisk, and the phenomenal 1927 Casavant repurposed by Schantz for St. Andrew’s Lutheran Church in Mahtomedi. Lise Schmidt’s welcoming article gives a sense of area history, punctuated by still more organ photos. The Calendar highlights US Holidays and the major dates of the Christian and Jewish year.
