Philipp Hyacinth Lobkowitz (c. 1772–1816) was a Bohemian nobleman and composer, whose contributions to music were noteworthy during the late Classical period. He is primarily associated with the genre of orchestral and chamber music. Lobkowitz was also a patron of the arts, supporting many prominent composers of his time, including Ludwig van Beethoven, who dedicated several works to him. Notable works by Lobkowitz include his symphonies and string quartets, which reflect the stylistic transition from the Classical to the early Romantic era. His orchestral compositions often featured innovative orchestration and a lyrical quality that appealed to the tastes of his contemporaries. Lobkowitz’s impact on music extends beyond his compositions; he played a vital role in fostering the careers of other musicians and composers, serving as a crucial link in the cultural exchange between aristocracy and the emerging middle class in early 19th-century Europe. His patronage helped to elevate the status of composers in society, making him a significant figure in the musical landscape of his time. While not as widely recognized today, Lobkowitz's contributions to music and support of the arts left a lasting legacy.
