In 1979, he graduated from the Katowice branch of the Jan Matejko Academy of Fine Arts in Krakow. He remained at the academy and worked as an assistant, from 1982 as a lecturer. In the 1980s, Tadeusz Biernot created surrealist paintings, illustrated children's books and designed posters. His posters received numerous awards: in 1976. - first prize for his design for the "Banner of the Young", in 1978. - first prize for a design for the Blood Donation Days, in 1978. - Gold medal in the poster competition of the Kyiv National University of Culture and Arts. The artist created many posters commissioned by an international student organisation in Prague. In 1979, at the Poster Biennale in Katowice, a poster designed by Biernot was awarded a silver medal. In the same year, the artist became a member of the Association of Polish Artists (ZPAP), Katowice branch. Between 1979 and 1989, while working at his alma mater, Tadeusz Biernot was involved in the reorganisation of the graphic design department and was one of the organisers and jury of the student drawing biennial. In addition to teaching and designing posters, Biernot illustrated books, as well as doing lettering and typography. He presented his paintings at the Biennale of Painting - Bielska Jesień and repeatedly participated in exhibitions of ZPAP in Katowice. His posters took part several times in the International Poster Biennale in Warsaw and the International Poster Biennale in Helsinki.

In 1983, a set of lettering designed by Tadeusz Biernot was awarded at the Typeface Design Competition in France.

Another book illustrated by the artist represented Poland at the International Book Fair in Bologna in 1985 and at the Children's Book Biennale in Barcelona in 1986. In 1989, Tadeusz Biernot had a solo painting exhibition in Ancona, Italy. In the same year, the artist took up residence in Italy. Contact with Italian art and culture, especially early Renaissance painting and the Italian school of frescoes, had a significant influence on his work.

In 1990, Tadeusz Biernot, together with his wife Ilona Biernot, a painter, emigrated to Toronto. During the initial phase of his emigration, the artist was involved in graphic design and continued his work as an illustrator. Between 1990 and 1996, he collaborated with the Globe and Mail newspaper, illustrated children's publications, and two lettering projects were included in international use by the Linotype Library. In 1992, Tadeusz Biernot's first solo painting exhibition took place at the PEKAO Gallery in Toronto. In 1995, the artist began designing posters for the Toronto cinema chain, Cineplex Odeon, and the Toronto International Film Festival. The poster for The Hanging Garden was selected as the best film poster of the Toronto Film Festival's 25th anniversary poster review. In 1996, as part of his collaboration with the Maria Nowotarska Salon of Poetry, Music and Theatre in Toronto, Tadeusz Biernot created a poster for the show "Great Revue of Hits".

He also collaborated with The Hudson Bay department store, for which he did drawing designs for an advertising campaign. In collaboration with large advertising agencies, the artist prepared advertising animation for companies: BMW, Honda, Oil of Oley. His project for the television channel Space received the Gold Medal at the PROMAX Broadcast Design Awards in New York in 2003. Combining his experience in lettering and illustration, Tadeusz Biernot became involved in creating animated opening credits for feature films, of which 'Jacob Two Two', from 1999, was the first project for which the artist designed subtitles. His next headlining projects were: "Joan of Arc" from 1999, "Nuremberg" from 2000, "Soul Food" from 2000, and "The Handler" from 2003. As art director of Barking Hot Studio, the artist was successful in creating a new layout for Fashion magazine.

Since 2005. Biernot decided to focus exclusively on painting, considering it his first vocation. He does easel paintings, usually large planes, painting portraits of famous people or faces he has imagined, often reminiscent of early Renaissance frescoes in character. Texture and colour play a significant role and create the mood of this painting. Faces in their entirety, or parts of them, eyes, mouths, emerge from a plane veiled in mist, blurred like frescoes patinated by time. Mysteriousness, sensuality and moodiness are the strength of Biernot's paintings, which combine aestheticism with emotionality and originality. The artist confessed in an interview that he is fascinated by capturing the relationship between beauty and emotion, capturing the moment of sudden awe. Light plays an important role in the creative process; it is thanks to light that the faces in Biernot's paintings emerge from the darkness and gain life.

Tadeusz Biernot has created a series of portraits of television personalities, well-known stars of opera, ballet and film, which has received much attention. In his latest formal explorations, the artist uses the pages of colour magazines to create the texture and structure of his paintings. Pasted onto the canvas, the artist tears off newspaper fragments and an uneven, colourful surface is created.

Tadeusz Biernot's works can be found in private collections in Canada, the United States, the United Kingdom, Italy, Germany and Poland.

Selected exhibitions by the artist: Trialogue - One Man Show, Leonardo Galleries, Toronto, 2014; Layers - One Man Show, Articsok Gallery, Toronto, 2013; Faces - Individual Exhibition, BWA Gallery, Bielsko-Biala, 2012; Side by Side - Ilona and Tadeusz Biernot, Hamilton Conservatory for Arts, Hamilton, 2012.

Work in catalogue
Tadeusz Biernot, 'Portrait', 2019, oil on canvas, mixed media, 137 x 150 cm. This is one of Tadeusz Biernot's recent works resulting from his formal explorations. The artist pastes pages from colour magazines onto the canvas, which creates the texture and structure of the painting, then peels off the fragments to create an uneven, coloured surface, which in the case of this work has become the outline of a woman's face. In an interesting way, Tadeusz Biernot's search for artistic and formal expression interacts with the art of recycling.
