Two more books in the Now You Know Bio series are scheduled in 2015.
Colorado placer miner turned naturalist Edwin Carter became concerned about the environmental impact of mining and feared that many bird and animal species might disappear from the Rocky Mountains. He collected hundreds of specimens for his Log Cabin Naturalist Museum in Breckenridge. At his death in 1900, Carter's collection became the basis for the Denver Museum of Nature and Science.
Thomas Price is author of the Edwin Carter biography.
Perhaps second only to General William Palmer in his contributions to Colorado Springs and the Pikes Peak region, Penrose's influence continues to this day.
Joyce B. Lohse's biography of Penrose is her fifth book in the Now You Know Bio series.
