In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: The attribution of the panel reflects the progression and trends of 19th and 20th-century scholarship on Early Netherlandish art. It is now thought to have been completed c. 1438–40, but there are still arguments for dates as early as 1424–29. As with the pages ascribed to Hand G in the Turin-Milan Hours manuscript, the panel was attributed to Jan's brother Hubert van Eyck in the 1875 Gemäldegalerie catalogue, and by a 1911 claim by art historian Georges Hulin de Loo. This is no longer considered credible and Hubert, today, is credited with very few works. By 1912 the painting had been definitively attributed to Jan in the museum catalogue.Attempts to date it have undergone similar shifts of opinion. In the 19th century the panel was believed to be an early work by Jan completed as early as c. 1410, although this view changed as scholarship progressed. In the early 20th century, Ludwig von Baldass placed it around 1424–29, then for a long period it was seen as originating from the early 1430s. Erwin Panofsky provided the first detailed treatise on the work and placed it around 1432–34. However, following research from Meyer Schapiro, he revised his opinion to the late 1430s in the 1953 edition of his Early Netherlandish Painting. A 1970s comparative study of van Eyck's 1437 Saint Barbara concluded that Madonna in the Church was completed after c. 1437. In the 1990s, Otto Pächt judged the work as probably a late van Eyck, given the similar treatment of an interior in the 1434 Arnolfini Portrait. In the early 21st century, Jeffrey Chipps Smith and John Oliver Hand placed it between 1426 and 1428, claiming it as perhaps the earliest extant signed work confirmed as by Jan.
What is the full name of the person who is credited with very few works?
