Harry Halff Fine Art began the Julian Onderdonk Catalogue Raisonné Project in 1996. After more than two decades of research, the Julian Onderdonk Catalogue Raisonné Project now includes a database with more than 1200 works photographed and catalogued, 237 objects and 480 personal letters transcribed, catalogued and archived. Along with this comprehensive collection of research material, Dr. Emily Ballew Neff contributed a scholarly essay for the catalogue.


The Museum of Fine Arts, Houston’s initial involvement with the Onderdonk Catalogue Raisonné Project began in 2003. From its very beginning, the Museum of Fine Arts, Houston, has been committed to collecting, studying and promoting Texas art. The museum’s curatorial, publications, development and rights and reproductions departments contributed essential time and expertise to this project. The Julian Onderdonk Catalogue Raisonné was published in October of 2016.


We are still interested in receiving any information concerning paintings and drawings as well as letters and documents concerning Julian Onderdonk or his works. There is no charge to authenticate works by Julian Onderdonk.
