Darwin Dale Klug

February 4, 1959May 5, 2021

Darwin Dale Klug, 62, of Maitland, Florida, passed away on May 5, 2021, following a most courageous battle with cancer.

He was born in Waterloo, Iowa, on February 4, 1959, to Dennis & Frances (Nierman) Klug. The family moved to Lakeland, Florida, when Darwin was in elementary school.

Darwin inherited his interest in pipe organs from his father, who was both an organist and a builder who started his own company in Lakeland, spending time with Darwin and his brother David in that endeavor. Darwin had a special affinity for the craftsmanship of tracker pipe organs, spending his career designing, perfecting and delighting in these grand instruments after graduating from Valparaiso University with a bachelor’s degree in political science. He built and left a legacy of both sight and sound, including founding Heissler in America to bring his custom organ designs, executed with German craftmanship, to the United States, including as far away as Honolulu. He loved working and traveling in Germany and the wonderful friends he made there. He met his wife and best friend Angela thanks to a pipe organ he installed in the home of her neighbors.

Darwin was easy to like and lots of fun as well as patient, kind, sweet and conscientious. He always strove to do the right thing. He loved his family, Bach, history, politics, Hemingway, Napoleon and L.A. (Lower Alabama) gumbo. Most of all he loved being with his son Brian, fellow Organ Guy, with whom he roamed the state and other parts of the Southeast on their many pizza-filled tuning trips. He was the best of dads.

Darwin’s positive spirit left us too soon, we miss him deeply, and we will continue to celebrate him and his very well-lived life.

Darwin is survived by his wife, Angela Klug, and son, Brian Klug; mother, Frances Klug; sister, Phyllis Allmon (Randell, dec'd), and brother, David Klug; niece, Julie Allmon, and nephew, David Allmon (Destany), as well as many other beloved relatives.

A Celebration of Darwin’s Life will be planned for later this year. Details will be posted here on this site.

Darwin's entire life consisted of love for his family and a passion for his life's work. He was my right-hand man for every Heissler Organ series concert that I produced. In fact, I saw Darwin as co-producer. I handled the "front" of the house and he took care of the "back". He was a wonderful friend to me for almost twenty years and he will be sorely missed by my wife, Susan and I. If I had unlimited space to write here, I'd start telling some great Darwin stories, and there are many! Requiescat in pacem, Dar.

Darwin was a wonderful human being, and I am shocked and saddened to hear of his death. I’m glad my dad, Bob Setzer, isn’t still alive as this news would’ve been devastating for him. He was so fond of Darwin.
My deepest sympathy to all his family.

I was so sad to hear of Darwin's passing. He was a light in the world and we always looked forward to his visits with us at Emmanuel to work on our tracker organ. His love for his work was apparent, and he always made our church music sound its very best! Brian regularly came with him and I loved to hear him on the piano!

We will miss Darwin and send our prayers and love to all his family!

Darwin was a good friend who always came to service the organ at our church. While working with him, it became very clear that his love for organs and the music they create guided his work and care. We will miss his wonderful charm and want his family to know that we will never forget the many hours he spent helping to keep our instrument tuned and running. Rest In Peace, good sir.

It seems like an eternity since I first met Darwin through his association with the German organ builder Heissler. I was first a customer purchasing pipe organ components from Germany via Darwin,
then a personal friend which occurred very quickly, since Darwin was very much an magnetic people person. We attended memorable wine festivals in Germany and collaborated on several pipe organ projects. My wife and I attended Darwin's marriage to Angela, and had the honor of meeting Brian, their son.
My sorrow can't ever be fully expressed with his passing, and my truly sincere condolences to his family.
