I had the privilege of attending a presentation he gave at the 2014 INPAWS Conference in Bloomington, Indiana. I always loved monarchs, but fell in love with them after learning about his life’s work, his observations of the creature, and the threats to the migratory monarch population. I was enthralled. This is when I decided I absolutely had to see the monarch’s winter home in Mexico some day and plant more milkweed.

His obituary appeared in The New York Times on July 24, 2018. Thank you, Dr. Brower.
