An artist-in-residence is a good gig, a job where an artist gets to create on site. The Bernheim Arboretum and Research Forest has an artist-in-residence program for those who wish to create in the great outdoors. Bernheim was established in 1929; “Bernheim: A Natural Muse” commemorates the 35-year-old artist residency program with works by 27 artists. “Art and nature have long been close companions in the human psyche,” says Carnegie Center curator Daniel Pfalzgraf. “For as long as humans have been creating artwork, artists have been divining inspiration from the natural world around them.” There will be many free public programs during the exhibition; details are on the Carnegie’s website. The opening reception is Friday, Jan. 22 at 6-8 p.m.
