Alfred Laurens Brennan (1853-1921) was an American painter, etcher and illustrator.
He first studied art at the University of Cincinnati School of Design. He moved to Philadelphia for a period of two years and worked with Frank Duveneck. Alfred Brennan then settled in New York in 1879 and began a very successful career as an illustrator for such national publications as The Century, Life, and St. Nicholas. He also illustrated a number of children's books.
As both an artist and illustrator Alfred Brennan was held in the highest regard for his art in black and white. Both his etchings and pen and ink drawings are brilliantly designed. One writer states that Alfred Laurens Brennan created "his own technical virtuosity and an unconventional point of view which makes his work always arresting and intriguing."
