Remsen was the author of children's plays notably Inchling and Mr. Blunt, he produced at the Forest Theater in Carmel-by-the-Sea, California in the 1920s.

He mastered portrait painting under Jacques Blanche and trained with painter Jean-Paul Laurens at the École des Beaux-Arts.

[7] While living in Greenwich Village, New York, Remsen stunted a fake marriage to Marie Centlivre, born of French parents in Indiana, on April 27, 1917.

"[11] On August 3, 1928, Remsen's play Inchling was presented at the Forest Theater for the second time under the direction of Garnet Holm.

It is also a play and was produced in the Carmel last summer-in the Forest Theater, surely a perfect setting for this whimsical fantasy of child and adult make believe.

Mr. Bunt, who was "made up" by Annie as she crooned the classic "bye, Baby Bunting" to her doll, is a distinct addition to the small group of Twentieth Century fairies-though he isn't rightly a fairy at all but an "invisible playmate," a new-fangled name for an ancient and honorable order.

"[15] In August 1925, Remsen went with painters Ray Strong, Ferdinand Burgdorff, and Frank Van Sloun for a two-month sketching trip to Grand Canyon and Flagstaff, Arizona.

Strong wrote: "Ferdinand Burgdorff and Ira Remsen, the artists, have gone to Flagstaff after a month spent vegetating at the Grand Canyon and gathering up scenery on canvas.

[18] In April 1946, the portrait was on display at the Carmel Art Association and then went as a gift to the Robinson Jeffers collection at the Occidental College library.

[20] Remsen's father died at Carmel's Pine Inn on March 4, 1927 and his ashes were sent to Johns Hopkins University.

[23][24][25] In February 1928, Remsen displayed two paintings, Cathedral Rock and Hopi House-First Mesa-Arizona, at the First State-wide Annual in Santa Cruz, California.

During the spring 1928, his watercolor Seagulls and Fishermen and several oils were exhibited at the Del Monte Hotel Gallery.

[28] In November 1950, the Harrison Memorial Library held an exhibit honoring Remsen with a display of his published works including Mr. Bunt, Inchling, and The Tinsel Angel programs of performances given at the Forest Theater, and the three-sided stage set for the production of Mr. Bunt.
