Martz’s first exposure to a professional ceramic art studio was in 1931 when he attended a summer course at Ohio State University. For the summer of 1932, the Griffith Pottery in tiny Nashville, Brown County, Indiana (a tourist destination and artist’s colony) hired Martz to improve their glaze formulas. In 1933, Martz graduated from Indiana University, Bloomington, with a bachelor’s degree in chemistry. He worked again at the Griffith Pottery in summer, 1933. In 1933-34, Martz returned to Ohio State University to do graduate work in ceramic art with Arthur E. Baggs, Carlton Atherton, and Edgar Littlefield. He then worked for a year as an apprentice at the Brown County Pottery. In 1935, he married, and began a series of rustic studios in the woods near Nashville, Indiana. 
In about 1936, Martz was discovered by his subsequent patron Scott Murphy, an art collector who had a summer home in Nashville, Indiana. Murphy funded Martz to move his studio from its remote location in the woods to downtown Nashville, where many more tourists would encounter his work. Murphy also funded a new showroom.
During the period from 1935-1942, Martz was enormously productive, making colorful earthenware. In 1936 and 1937, starting at age 24, his work was exhibited in the National Ceramic Exhibition in Syracuse, New York, and included in the exhibit circuit. This was the first of widespread recognition he achieved during the remainder of his life (see Recognition). Nationally syndicated journalist Ernie Pyle described Martz in 1940 as follows:
Karl Martz is reticent, low-spoken, gratefully polite. He does not speak in arty terms. ... The parlor of his home is the exhibition room. In it today stand the most beautiful pieces of pottery I have ever seen. Each piece is an individual thing, almost with a soul. He never makes a duplicate of anything. ... The ingenuity and artistry that he fashions into his clay are actually touching. (Newspaper clipping and subsequent correspondence.)
By 1942, tourist traffic in Brown County, Indiana, had largely ceased due to World War II gas rationing. For the remainder of the war, Martz did research in ceramics at Carnegie-Illinois Steel Company and Armour Research Foundation in Chicago, Illinois. In 1944, he taught ceramic art part time at the Chicago Institute of Design directed by László Moholy-Nagy, and at Hull House, where the family lived.
In Spring, 1945, Martz was hired by Henry Radford Hope. Hope chaired the Fine Arts Department (later the School of Fine Arts) at Indiana University from 1941 to 1968. Martz began as Instructor of ceramic art. Ceramic equipment was difficult to obtain after the War, so the University bought all the equipment and supplies from Martz’s earlier private studio.
Martz achieved national and international recognition over the next four decades, both as an educator and as a ceramic artist (see Recognition). In the 1950’s, he began doing sculptural work in stoneware and later, Asian-inspired porcelain, as well as continuing functional and sculptural earthenware. In 1952, Martz participated in the seminal summer workshop at Black Mountain College, North Carolina, working with Bernard Leach, Shoji Hamada, Marguerite Wildenhain, Peter Voulkos, and Warren MacKenzie. In 1957, Martz and Harvey Littleton spent ten days at the historic Jugtown Pottery near Seagrove, North Carolina, where they learned traditional salt-glazed stoneware techniques. In the 1960’s and 70s, he did two sabbatical semesters in Japan (see Sabbaticals), which influenced his work. In 1965, he was elected President of the Design Section of the Ceramics Education Council of the American Ceramic Society (ACS). In 1966, he was a leader in the separation of that group from the ACS and the founding of the National Council on Education for the Ceramic Arts (NCECA). In 1992, he was inducted as a Fellow of the American Craft Council.

Karl Martz was born in Columbus, Ohio, USA to Velorus Martz (high school principal and later Professor of Education at Indiana University) and Amy Lee Kidwell Martz.
While I was in high school [1925-29], the whole family took a motor trip through the West. The car got into the sand in New Mexico and ripped out its differential, and we were stuck waiting for its replacement. So we put up our tent and stayed a couple of weeks. I entertained myself in part by making little pots and firing them in a pit -- I'd read the Indians did this. I still have one of them.
Wife, Early Studios, & Children
Martz graduated from Indiana University in 1933 with a batchelor’s degree in Chemistry. In 1935, he married Margaret Rebekah “Becky” Brown. Initially, they lived in a small cabin on a hill just South of Nashville, Indiana, where Karl built his first kiln:
"I built a kiln out in the woods. Didn't know a thing about building kilns, of course. I got a big 20 gallon stoneware crock, knocked the bottom out to get a draft, and put a pan underneath to drip oil into so the flame would come up through. Can you believe this? It smoked terribly -- great clouds -- and the neighbors thought we were running a moonshine still. But I could get copper reds on the bottom and chrome reds on top, all in the same firing. Pretty soon I talked my dad into financing a real kiln."
Soon they rented a cabin in the woods, North of Nashville, Indiana, where Karl’s father-in-law helped to add a studio room to the house. Later they had several studio-homes in the tourist town and art colony of Nashville, in Brown County, Indiana. They had two sons, Eric in 1940, and Brian in 1942. Becky learned ceramics from her husband, initially making small items to sell to tourists. Later, Becky developed her own style, making charming and whimsical animal sculptures, and earning a regional reputation.
Martz Studio & Bloomington
Martz designed a home and studio on the outskirts of Nashville, Indiana, the ‘’Martz Studio’’, and built it largely with his own hands, starting in 1949. In 1954, the family took up academic-year residence in Bloomington, Indiana, to enable their two boys to attend the University School, which was academically much superior to the school in Nashville IN. Eric became a professor of biological science, and Brian, a musician and professor of music. Martz and his wife continued to spend weekends and summers at the Nashville Martz Studio, making and selling pottery there, until 1961, when they sold it and moved to a modest home at 105 N. Overhill Dr. in Bloomington, Indiana, where their lives had become centered. They converted the attached garage into a ceramics studio, where Martz and his wife continued to make pottery and ceramic sculpture until precluded by failing health. Upon Martz’s death in 1997, they had been married for 62 years.
Martz had an unassuming and modest demeanor, preferring to be called a potter. He battled life-long depression. In the late 1930's/early 1940's, he enjoyed acting in plays (some written or directed by Joseph Hayes) at the Brown County Theater. He played the piano, mostly boogie woogie, sometimes entertaining his children and nieces with musically-accompanied stories.
Decline and Death
In his final years, Martz battled metastatic prostate cancer, became nearly blind due to macular degeneration, and also suffered significant hearing loss. Shortly before his 85th birthday, unable to recover from gall bladder surgery, he died from natural causes (Obituary). His wife Becky declined with a gradual dementia, living until 2011, age 96 (Obituary).

- Throwing (1950, 11 min)*
- Decoration (1952, 11 min)*
- Simple molds (1954, 11 min)
