This is just terribly sad news.

Just learned the chilling news about Denny. What gracious good humour, wit and wisdom we are losing.
I am not ashamed to say I am weeping as I type this.
There’ll be a new star in the heavens when he’s gone , one to remind us, whenever we look up to the night sky.

Denny is a very dear friend…the light and laughter he brought to our lives will forever be missed. Thank you for everything you’ve given us, Denny. Much love being sent to you and your family.
The playful sparring relationship I had with Denny here at C&F was a pleasure I looked forward to, but it was also a challenge, because he had an unending talent for firing from out of left field like no other. Kept me on my toes, he did.
I was trying to be sanguine about this, but I cannot. I am shocked and gutted, as I was by the news of Devondancer and Roland’s death. I hear about death daily as if from a vast distance and it doesn’t feel like it touches me. Until one day the loss of someone with whom I’ve never even shaken hands fills my eyes.
Your terse epistles and sudden right turns often drove me to distraction, denny, but I will miss them like the dickens. This place will be poorer without you.
I ended up in my inbox today…the first time in a very long time. There was a rather humorous discussion with Denny there (from 2010!), about how he would look in a Rumba dress. It was a good memory 
But, it still brought many tears with it. I reiterate, he will be missed very, very much.
Denny, rest easy mate… a final sailor’s salute and God Bless
He will definitely be missed. Good flight, Denny! And the Great Galactic Session Circle adds another chair.
Denny is a true gift to this community. He will be remembered for his intellect and awesome sense of humor. My condolences to all who loved and appreciated him.

I’m late here, but so sorry to hear about this. Denny will certainly be missed. My thoughts are with his wife and family.
This is such sad news. I too had wondered at his absence lately but never dreamed it was due to something like this. There are a few folks that we meet- whether in the flesh or online- that enrich our lives. Denny was one of those- on these boards, many years ago, I struck up a friendship with Denny, through our love of music, learning and horses. Like others here, I too will miss him terribly.May his passing be easy and the next pastures be filled with joy.
I am so sorry to learn this news. Lovely person.
Denny was one of those wonderful individuals that make this board so much more than just a technical resource for whistles. I will certainly miss his humor and facinating astronomical posts (I’m still using one as desktop background on my computer, and I tend to cycle between several favorites). Wish I could have met the man in person.
My condolences to his loved ones
My thoughts are with Denny and his family during this transitional period… may his remaining time here be blessed with grace and ease, and may his family and friends find peace in the time following.
This is the worst news I’ve had in a long while…so sad.
I’ll miss you mate..
Facebook posting by Adena, his wife, tells us that he passed last night.
