Dr. Bernie Krause is both a musician and a naturalist. During the 1950s and ‘60s, he devoted himself to music and replaced Pete Seeger as the guitarist for the Weavers. For more than 40 years, Dr. Krause has traveled the world, recording and archiving the sounds of creatures and environments large and small. He has recorded more than 15,000 species and 4,000 hours of wild soundscapes, over half of which no longer exist in nature due to encroaching noise and human activity. Dr. Krause and his wife, Katherine, live in California.
