Keller, Bill: - Wendelin (Bill) Keller is a freshwater biologist who has studied lakes and rivers across northern Ontario, Canada, for over fifty years. Much of that work was done in the far north, the vast, wild part of Ontario that starts where the allseason roads stop and extends up to the shores of Hudson Bay and James Bay.

Bill is a senior research fellow and an adjunct professor at Laurentian University. He has authored or co-authored well over a hundred papers in scientific journals and ten chapters in science books. He is also a freelance writer and has published dozens of articles in outdoor magazines. When not working in nature, Bill has usually been out playing in it, enjoying one outdoor activity or another. He lives in Sudbury, Ontario, with his wife, Wendy.
