C. Wilhelm

[1] The young artist showed early promise, and J. R. Planché recommended him to design for the Theatre Royal, Drury Lane.

[4] He was the designer for some of the costumes in several of the original Gilbert and Sullivan operas at the Savoy Theatre in the 1880s, including Iolanthe, Princess Ida, The Sorcerer (revival), The Mikado, and Ruddigore.

Wilhelm's costume designs were seen on Broadway in Ruddigore (1887), A Runaway Girl (1898–99), The Toreador (1902), Three Little Maids (1903), The Babes and the Baron (1905–06), The Red Mill (1906–07), The Soul Kiss (1908), The Silver Star (1909–10), The Old Town (1910), The Arcadians (1910), The Girl in the Train (1910), The Lady of the Slipper (1912–13), Chin Chin (1914–15), The Yankee Princess (1922), Stepping Stones (scenic and costume design, 1923–24) and Madame Pompadour (1924–25).

[5] London's The Times wrote, "Wilhelm excelled especially in rendering the spirit and detail of historical periods, but he had also an amusing skill in turning modern costumes to his fantastic purposes.... to his imaginative gifts he added remarkable precision and firmness in execution and great ingenuity in the treatment of colour.

In his last years, he focused on watercolour painting, especially of flowers and plant life, and illustrating children's books, including The Child of the Air, and he was elected to the Royal Institute of Painters in Water Colours in 1920.
