Leo's wry smile today is the same as it was when we were high school students at Cathedral Latin School in Cleveland...somewhat wry, knowing, wise. He was one of the bright guys that you wanted next to you at that algebra test, just in case you wanted a peak at the right answer. He was always quiet, unassuming, but you knew that his brain was always working, taking in the crazyiness and the wonder of those years. Peace be with you, Leo.

I had 9th grade Biology with Mr. deininger in 1964(?) at Collinwood High School. He was a great teacher and taught us way more the suggested curriculum. A good man. Rest well Sir Duane Elersich.

Ruth, so sorry to hear of the passing of your beloved Leo. Was introduced to Leo and you by my sister, Louise McDonough. Always great conversations on many topics, especially on birding with Leo and John Nelson. Know he loved nature and The Cleveland Hiking Club. He will be missed by many.

Ruth, My sincere sympathy. I have great memories of Leo from our teaching days long ago at Collinwood. He was one of a kind.

Ruth, our sincere condolences to you. We've always enjoyed yours and Leo's company. I know you'll be lonely without him, and he'll no doubt be missed by many others. We're here for you; stay in touch. Your friends and neighbor, Ray and Cathi
