He was often heard saying things like Guts Nächtle, which would be the equivalent of Gute Nacht in High German (or good night in English).

Paetsch was very young during World War II in Stuttgart, and everything in his parents' home and its surroundings were destroyed by the aerial bombing.

On November 22, 1942, Paetsch's mother, Helena Maria, died while she was in the hospital as southern Stuttgart was attacked by 191 aircraft during a bombing raid in the early morning hours.

The next night, there was a big bombing raid with search lights all over the sky looking for the airplanes, and ground forces firing back.

Because almost everything was destroyed, he taught Paetsch while sitting on potato crates in the ruins of the war, and as Hadelich's children (Sigismund and Valeska) were then babies, they were surrounded by the smells of diapers.

Paetsch later took lessons with the Spanish cellist Gaspar Cassadó in Tübingen, Germany, who only taught two students privately during 1956–58.

[4] Paetsch was educated with Abitur or Reifezeugnis ("certificate of maturity"), the prerequisite for matriculation at a German university in the subjects of science, mathematics and languages, from the First Waldorf School in Stuttgart, Germany.

[1] He obtained working experience from 1953 until 1956, with some interruptions, to earn a master's degree at the Robert Bosch GmbH in Stuttgart (which had around 28,000 employees) as a mathematician in the Department of Corporation Insurance.

[7] In Tübingen on February 21, 1957, Paetsch (then 28) met the young 26-year-old American violinist Priscilla McClure Johnson, who was on a world tour at the time, and they fell in love.

[7] Paetsch came to the United States in 1959 not only to see where and how Priscilla grew up (she also trained Polish-bred registered Arabian horses), but also to marry her.

His first job in the US was as a horse riding instructor and soccer teacher at the Lowell Whitman School in Steamboat Springs in 1959, after his honeymoon.

Günther Paetsch was principal cellist in the Colorado Springs Symphony Orchestra through three conductors: Walter Eisenburg, Harold Farberman and Charles Ansbacher.

He was a founding member and cellist of the string trio called the Sebastian Players, which included Jim Boratgis on the viola and Priscilla Paetsch on the violin.

Among other biological and physiological instruments ready for production was the first solid state laboratory stimulator to study nerve potentials and intercellular potentials of cardiac cells for physiological research, pacemakers for heart stimulators, cardiac defibrillators and micro electrode pullers for making both glass micro-electrodes with points from 1 to 3 microns and micro-glass tips for embryo-logical research.

[12] With this group, he and Priscilla taught, rehearsed, and performed with their children most of the chamber music from duos to nonets in and throughout the Colorado area.

Michaela, the second oldest, broke new ground by joining the Colorado Springs Symphony Orchestra at age 13, making her the youngest member ever.

The ensemble gave concerts for fund-raising projects and to the community in the Penrose Public Library, in the Fine Arts Centre, for the Ute Symphony Guild, on television, for numerous churches and civic organizations, and for the City of Colorado Springs in its celebration of Heritage Day at the old courthouse.

The Pueblo Chieftain wrote: "The Paetsch Family is truly gifted in terms of discipline, talent and the desire to give of themselves.

Günther and Priscilla built their house on the west side of Colorado Springs (in upper Skyway) in 1967 and called it "Cosmic Heights".

He did all the development and enlarging of negatives and prints in his own darkroom in the basement of Cosmic Heights, and his photos were often published in various magazines and newspapers.
