MARK CHRISTOPHER MUELLER, age 75, a native Dallasite, passed away on Tuesday, August 18, 2020. He displayed an ability during his lifetime to conform to unforeseen and changing circumstances, and tended to take his work seriously, but himself not very seriously. He was born June 19, 1945, at St. Paul Hospital, Dallas, the only child of Herman August Mueller and Hazel Dean Hatzenbuehler Mueller, both native Dallasites.

Herman Mueller’s family included his paternal grandfather, August Mueller, who came to Texas shortly after The War Between The States and engaged in the occupation of a building contractor, cabinetmaker, and organ builder. August Mueller had previously worked in the churches and cathedrals of Europe and had served as a guard in the Vatican. Later in life, August Mueller operated The Blue Front Saloon in downtown Dallas, which became a German food restaurant.

Herman Mueller’s maternal grandfather was Christian Moser, who came to Dallas in approximately 1870 and engaged in the dairy business, as well as real estate development with his wife Anna. Christian Moser married Anna Buehrer whose family had come to Dallas and established a dairy where White Rock Lake is located. Together they had six children, including Herman’s mother, Frieda.

Mark’s mother Hazel (one of eleven children) was a descendant of T. C. Hawpe, who served two terms as sheriff of Dallas County and in the Confederate Army as a colonel. Hazel’s father was George Washington Hatzenbuehler, Sr., whose family had come to Dallas after The War Between The States and engaged in farming activities, as well as being a Teamster for the Railway Express.

Mark was fortunate enough to have been able to attend Lakewood Elementary School, J.L. Long Junior High School and Woodrow Wilson High School. He obtained admission to Southern Methodist University where he earned a Bachelor of Arts in Economics, a Masters of Business Administration in Accounting, and a Juris Doctorate degree. While in school, Mark was able to pass the CPA exam on the first try and somewhat distinguished himself in academic performance in law school, receiving the Order of the Coif and ranked 5th in a class of 130. While in law school, Mark served as leading articles editor on what became the SMU Law Review and as an instructor in legal writing and research.

Upon graduation, the economy was in a certain amount of distress, so Mark proceeded to work with L. Vance Stanton for one year as an attorney and later went into solo practice in association with attorneys Tom A. Boardman and Paul Don Wilmarth, and was a member of “The Three Musketeers.” Over his protests, Mark was called back to SMU Law to serve as an adjunct professor to fill a need in the faculty. He practiced the general practice of law related to real estate and business transactions for a period of approximately forty-plus years. He was gratified to receive the AV rating from Martindale Hubbell and to be included in Who’s Who in America – General Edition and Law Edition. He understood that he was included in U.S. News and World Report of Attorneys.

Mark engaged in a number of civic activities, including his college fraternity of Sigma Chi where he served in a variety of functions and offices, both undergraduate and alumni. He further served as a Lodge Officer of his Masonic Lodge, Hillcrest No. 1318, and as Worshipful Master in 1981-82. He affiliated with his ancestral lodge, Tannehill Lodge No. 52, where his great grandfather August, and great great grandfather T.C., had been members and officers and served as an affiliated Past Master. He attempted to perform whatever duties the Lodges requested of him. He was appointed 17th Degree Master at Scottish Rite in Dallas and served in that position for thirty years. He received the 32 degree Knight Commander Court of Honor from Scottish Rite in 1991 as well as 50 years of service award and various other honors from Masonic lodges. Mark had been a member of the Grotto and York Rite bodies.

Mark joined and served in the Sons of Republic of Texas and was the Chapter President of Thomas J. Rusk Chapter. He later joined the Sons of Confederate Veterans and twice served as Camp Commander of Gaston Gregg Camp. He was one of the founding member of the Lone Star Camp and Texas/Oklahoma for the Sons of Union Veterans in North Texas, but did not pursue further activity. Mark additionally joined the Sons of the American Revolution, Plano chapter but was not able to find time to contribute significantly to the organization. To further his historical organizations he was a member of Dallas Historical Society and Military Order of Stars and Bars.

Mark, in addition to other Bar activities, served a number of years in the State Bar on the Unauthorized Practice of Law Subcommittee handling assigned matters relating to consumer protection by the State Bar. At the time, his activities resulted in the largest recovery of improper legal fees by the Committee. Mark joined and served in various positions in the Dallas County Pioneer Association. He also was a life member of the Dallas Safari Club and Dallas Arms Collectors Association, a defender member of the Texas State Rifle Association, a benefactor member of the National Rifle Association, and enjoyed hunting when he could find the time to do so. He was a life member of Rock Creek Barbeque. Mark was a lifetime member of East Dallas Christian Church almost from birth.

Mark married Linda Jane Reed Mueller, native of Massachusetts, and they have one child, Amy Lynn Mueller of Dallas.

He was an initiator of a joint family reunion of the Moser, Buhrer, Hatzenbuehler families that drew attendance by several hundred cousins.

Throughout his life he exhibited a humble attitude and was seriously concerned about the welfare of his fellow man and unconcerned about who received credit for his efforts.

Mark always obliged us with his knowledge of family history and humor. He was always smiling, and I guess that is the way I will forever remember him. I used to like to steal kisses on his cheek and make him blush. We had some great conversations but I still don’t know what it means to be given a penny and a knife (?). I could have listened to him tell stories forever. Although I never asked anything from him (other than the kisses), he was always offering advice. His greatest gift to me was the strength he lent me after the death of my father, his cousin. I have lost my sweet cousin, but only for awhile. Janie Hatzenbuehler

I met Mark at one of Willetta's happy hours for tenants of the Square. We got to talking and found out we had several mutual friends. He knew them from the Sons of Confederates and I knew them from the Southwest Celtic Music Associations. Mark was always a good friend and later invited me to some masonic events. Then we became masonic brothers. And lastly, he became my family's attorney. Life has a tendency of keeping everyone busy; however, I will never forget Mark's friendship and words of wisdom. And will deeply miss him. However, I do have a photo of him with my family and friends at my masonic bible presentation (which I deeply cherish).

Linda and Amy, my deepest sympathy and condolences to you both from me and my parents.

Linda and Amy,

Mark was Wiley Bros.’s smart, thorough, and loyal attorney for many decades. I have many good memories of working closely with Mark on legal matters related to our commercial landlord business and our construction business. You could count on Mark to dot every i and cross every t.

One of the peculiar benefits of being Mark’s client was receiving his yearly Christmas presents. We are not talking about a fruitcake or box of fruit or a favorite adult beverage. We are talking about unique, bizarre unimaginable gifts that only Mark could find and somehow think you might like them.

Mark, with his Santa Claus hat, would climb out of his BMW with multiple gifts wrapped humbly in saved Sunday color comic strips newsprint. The anticipation of what was hidden behind the comics and abundant scotch tape added to the yearly excitement. We created a shelf in the Wiley Bros. office cabinet for the saved annual gifts. To say they were an adventure would be an understatement!

Eventually most of them would be tried and used only to be returned to the shelf. Some themes became apparent such as knives, flashlights, personal protection devices. All of which you had never seen anything like them in your life. He clearly enjoyed sharing his strange Christmas bounty.

We miss his wit, hard work and ironic twists but know he resides now in a far better place. Rest In Peace, faithful servant.

It was special to meet the Mueller Family through the Children of the American Revolution back when Amy was young. Over the years I found the family so helpful and supportive of the Treaty of Paris Society sponsored by the Highland Park DAR Chapter.
Mark was a very dedicated man. Dedicated to God, his family, and his country. Indeed dedicated to all he held dear.
Know that we care deeply about the sadness you are going through right now. God will heal your heart in time.

Dear Mark's Family.........
I was very saddened to see his obituary a few days ago. It's been a while since our paths had crossed; but, I have many memories from the first time we met. I am a member and Past Master of Dallas Lodge 760 and through the years we would see each other at various Lodge and Scottish Rite functions. I thought the world of his uncle George Hatzenbuehler, too, from the first time we met in Lodge. It was he who introduced me to Mark. Mark was a fine man, a true gentleman and my Brother. I know he is missed by you and many, many others. May he rest in peace.

I was introduced to Mark by my mentor and, later, law practice partner, Ennis Walden, in the corridor just outside the 5th District Court of Appeals. Mark learned I was appearing before the Court of Appeals for the first time in my career. Mark advised me that, as Christians learn their faith from the Bible, so too, lawyers hone their professional skills by reading the law. His words, as I recall them, were: "Read the book to get the word."

Linda and Amy, I first met Mark at the Rock Creek Barbecue Club years ago. Then Mark joined the Dallas Arms Collectors Association so it seems that very often when I looked around there was Mark. He was always smiling and seemed to be happy to see you, whoever you were.
The first time I saw Mark in his wheel chair at the Gun Show it broke my heart. He was far to active to have to deal with that. But he did, because he had a big heart was a fighter to the end.
Mark Mueller was one of the most cordial men I ever met. He was a true Gentleman and he will be missed by all who knew him.
God Bless Mark Mueller's soul.

Dear Linda and Amy,

Regret so much the death of Mark. My thoughts and prayers are with you. I remember Mark vividly from childhood. Always staying with Aunt Thelma and Uncle Ernie on trips to Dallas, Aunt Thelma would burg us up to date on all activities concerning the family. Dad especially enjoyed these visits and hearing news of family. As an aside, did you know that Dad (Otto) and Herman were roommates right out of college: Dad A&M and Herman (SMU? not sure). At any rate, I've tried to keep up in memory of Dad even though there is a distance. Steve and I plan on attending the funeral if all goes well.
