David Croal Thomson, 1911 Encyclopædia Britannica (1911)
“ It was at the moment when the serial publication of Pickwick was in danger from the want of a capable interpreter for the illustrations. Dickens knew Browne slightly as the illustrator of his little pamphlet Sunday under Three Heads, and probably this slight knowledge of his work stood the draughtsman in good stead. In the original edition of Pickwick, issued in shilling monthly parts from early in 1836 until the end of 1837, the first seven plates were drawn by Robert Seymour, a clever illustrator who committed suicide in April 1836. ”
