John Atkinson Grimshaw (6 September 1836 – 13 October 1893) was an English Victorian-era artist who has been called a "remarkable and imaginative painter" best known for his nocturnal scenes of urban landscapes

Today, he is considered one of the most renowned painters of the Victorian era, as well as one of the best and most accomplished nightscape, and townscape, artists of all time.

Grimshaw's accuracy and drive for realism was criticised by some contemporaries, with one critic claiming that his paintings appeared to ‘showed no marks of handling or brushwork’, adding that ‘not a few artists were doubtful whether they could be accepted as paintings at all’. However, other contemporaries recognised his mastery of lighting and technique, and James McNeill Whistler, whom Grimshaw would go on to work with in his Chelsea studios, stated, “I considered myself the inventor of nocturnes until I saw Grimmy’s moonlit pictures”.
