Hi Mike,
Yes, that's me. I started collecting and hybridizing daylilies in 1980 while I lived in Michigan where I was born and raised. In 1984 I moved to New York and was a horticulture student at The New York Botanical Garden. This is where Dr. Stout did all of his genetic research on several plant genera including Hemerocallis (although his introductions were distributed by Farr Nursery in PA). His interest was in plant sterility, and that's what led him to work with H. fulva. After I finished the horticulture program at NYBG, I was offered a position working in the outdoor gardens...mainly raising, planting, and maintaining annuals, perennials, and bulbs. I became curator of the daylily collection, and refurbished the Stout Daylily Garden to include not only his cultivars, but all of the Stout Medal winners and species that Dr. Stout used to breed with. My coworkers and I also created several new daylily plantings featuring other hybridizers. I never met Dr. Stout (he died in 1957), but I did register a couple of his unnamed seedlings which were still growing on the grounds at NYBG and are the ones you saw on the ADS Database registered in 1987 and 1990. The registrar at the time insisted it would be a co-registration even though I felt they should bear Dr. Stout's name only. In 1996 I moved from NY to NC, where I still live.
I'm still hybridizing daylilies. Yellow has always been my favorite daylily color...it can't be beat for sun-fastness! And since the late 90s, I've also been breeding herbaceous peonies - although I've only registered one of these.
