Richard Diebenkorn's artistic contributions during the 1990s were shaped significantly by his work in the preceding decades, his health, and his legacy as one of the 20th century's most influential American painters. His passing in 1993 marked the end of an era characterized by the prolific creation of abstract and figurative art that captured the essence of California's landscape and light. The 1990s witnessed the continued recognition and celebration of Diebenkorn's art, both through posthumous exhibitions and the scholarly cataloging of his extensive body of work. Diebenkorn's artistic endeavors in the early 1990s, prior to his death, were constrained by health issues related to heart disease and emphysema, which limited his ability to produce large-scale paintings. Despite these challenges, he remained productive, focusing on prints, drawings, and smaller paintings. In 1990, for example, Diebenkorn created a series of six etchings for the Arion Press edition of Poems of W. B. Yeats, showcasing his adaptability and continuous creative output even in the face of declining health​ (Wikipedia)​. After Diebenkorn's death, the Richard Diebenkorn Foundation played a pivotal role in preserving his legacy and making his work accessible to a wider audience. One of the foundation's significant achievements was the publication of "Richard Diebenkorn: The Catalogue Raisonné" in 2016, edited by Jane Livingston and Andrea Liguori. This monumental four-volume catalogue documents over five thousand of Diebenkorn's works, including many that were unpublished or little known during his lifetime. The catalogue raisonné offers an exhaustive record of Diebenkorn's artistic journey, from his early abstract works to his renowned Ocean Park series, and includes an array of essays by noted scholars that explore the depth and breadth of his career​ (Richard Diebenkorn Foundation)​. Diebenkorn's influence on the art world extends beyond his physical creations. His work continues to be a subject of study for art historians and a source of inspiration for artists. The ongoing exhibitions and scholarly research into his oeuvre testify to Diebenkorn's enduring impact on American art and his significant role in the development of abstract expressionism and figurative painting in the postwar era. The cataloging of his work and the activities of the Richard Diebenkorn Foundation ensure that Diebenkorn's contributions to the art world will be appreciated by future generations.
