Lothar Max Ludwig Klingmuller

May 14, 1936January 29, 2020

Dr. Lothar Max Ludwig Klingmuller, 83, passed away on Wednesday, January 29, 2020.

Lothar was born May 14, 1936 in Bremen, Germany to Anne Lore Strack and Otto Klingmuller, and was the fourth of five children. Lothar’s zest and curiosity for life were evident in everything he did; he was known to say “just do it.” This attitude prompted his immigration to the U.S. at the age of 18 despite his lack of English and high school education. This same outlook on life led him from work as a pastry chef in Germany to three years of service in the U.S. Army. There his grave-digging duty sparked an interest in geology. Lothar secured his U.S. citizenship at the age of 26. Three years in the Colorado National Guard introduced Lothar to flying, which became a lifelong passion, eventually earning him the Wright Brothers Master Pilot award from the FAA. Lothar earned his undergraduate degree at the Colorado School of Mines and his Ph.D. in Mining and Geological Engineering from the University of Arizona. He received a Fulbright Fellowship to Australia.

He had a great love of the outdoors and even after traveling all over the world said that Colorado was the most wonderful place, which he called home. He was involved in the Colorado Pilots Association and voluntarily flew over 300 children in the Young Eagles Program in his own home-built airplane, the very same plane he flew all over the U.S. and Central America. He was also an active member of a German fraternity called Schlarafia for thirty-two years and Jefferson Unitarian Church in Golden. He passed on his love of the outdoors to his twin daughters and taught them to be self-reliant in all aspects of life. He will be most remembered for his love of family and friends and readiness to celebrate the beauty and miracle of life around us, most notably with an afternoon ‘Anlager.’

Lothar is survived by his daughter, Jenny Klingmuller Hochtl (Karl), grandchildren Annelore and Karl; daughter, Kelda Klingmuller Neely (Steve), grandsons Emmett and Matthew; brother Hartmut Klingmuller, nieces, nephews, and dear friends. Lothar was preceded in death by his parents, brother Olaf, sisters Karin and Gunda, and grandson Elliott.

A service will be held at Jefferson Unitarian Church,14350 W 32nd Ave, Golden, on Saturday, February 29 at 2:00 p.m.

I could not resist adding to my first post on the Summer of 1974. Kling must have worked in Southeast Alaska the Summer of '73 where weather was often challenging and it was difficult to get into the field to work. So, in the Summer of 1974 in the Brooks Range, Kling just hated to miss field work when the sun was shining. No matter if we started the day in the rain with work in the office tent, whenever the rain stopped and the helicopter could fly, it was automatically "8AM" and the real work day started. Happily Kling finally learned, after half the summer passed, that the weather in the Brooks Range was better than in Southeast.

Thanks to Jim Cappa for the notice about Kling. I also was a member of the 1974 summer crew in the Brooks Range with Kling and others. It was a memorable time in the field in a remote place. We all worked hard and when time was available played hard. Kling was a great first professional boss for me. He was a good leader, mentor and confidence builder. My only regret is not staying connected with him over the many years since.

Lothar and I met at Front Range Airport. His wit and wisdom will be remembered by all of us who were his aviation peers. As we say in the aviation community (and as Lothar frequently closed an e-mail with!): Smo-o-o-o-o-oth ride!

I have enjoyed knowing Lothar over the last 20+ years. We have hangared and flown together and shared Alaskan stories over the years. Lothar, I will miss you!

I worked for "Kling" during the summer of 1974 on a mineral exploration project in the Brooks Range of Alaska. Kling was a great boss and I enjoyed my time with him that summer. Later, I moved to Denver and eventually so did Kling. We both became pilots and shared the double whammy of geology and flying airplanes. He was an excellent geologist who worked well with others and he is sorely missed. The photo is of a training session that Kling led on a portable drill we had in Alaska.

It was a treat to work with Kling in northern Alaska. Photo of Kling in our camp at Crevice Creek ranch playing horseshoes after a day of fieldwork.

As member of Jefferson Unitarian Church, Lothar became a member of our Men's Group for more than 10 years.
We learned about his pride for his children, his love for flying, his continued expertise in preparing pastries, and most importantly his incredible love for the outdoors.
He will be greatly missed by our group.

I will always be grateful that Lothar hired women for work in Alaska . He told me that he was impressed with the women he worked with in Australia. His Company got flack from peers suggesting they should not have women doing fieldwork, but they continued to hire more women. My experience in the Brooks and Alaska Ranges, with him, had a profound affect on my career as a geologist. He also respected his mother, who, I believe was an agronomist. My best wishes to the family in this time of loss.

Lothar's smile, personal warmth, and generosity endeared him to me and to many other geological colleagues. We'll miss him as the years roll by, but his memory will always be there.
