He has also painted official portraits of Henry Kissinger, John Mica, and Jon Corzine, among others.

Bittinger made his debut as an illustrator in 1995 with the Passover Sedar fiction children's book The Matzah That Papa Brought Home, which was met with critical acclaim and became an American Library Association Notable Children's Book and a Notable Book for Younger Readers from the Sydney Taylor Book Award. He later illustrated The Blue and the Gray (1996) and Rocking Horse Christmas (1997), both of which received positive reviews from critics. In 2002, he illustrated his latest book, When the Root Children Wake Up, which is a retelling of Sibylle Von Olfers' book, The Root Children, originally published in 1906.

Ned Bittinger was born in 1951 in Washington, D.C. He started painting and drawing in the third grade. When he was age thirteen, his parents sent him to the Corcoran School of the Arts and Design of Washington, D.C. He attended Landon School in Bethesda, Maryland.

He left to attend Denison University in Ohio, where he received a Bachelor of Fine Arts. In an interview in 2017, Bittinger stated that he originally got an F grade in painting at Denison University.

After graduating, Bittinger briefly got a job at a commercial arts studio. He also began to practice Transcendental Meditation and would become a teacher of the technique. At age 28, he earned his Master of Fine Arts degree from the Corcoran School of the Arts and Design at George Washington University.

Bittinger has received awards and participated in many exhibitions, including an exhibition at the Tretyakov Gallery in Moscow from 1990 to 1991. Bittinger painted two portraits for the 1994 movie Guarding Tess, one of Shirley Maclaine and the other of her husband in the movie. In 2017 Bittinger estimated that he had painted between 400 and 500 portraits.

In 2004, the US House of Representatives commissioned Bittinger to paint the official portrait of Abraham Lincoln. The painting depicts Lincoln at a young age from when he served in the House of Representatives from 1847 to 1849. Ned Bittinger worked from photographs of Lincoln's time in Congress as well as historic images of the House Chamber. The setting includes the John Vanderlyn portrait of George Washington, furniture designed by Thomas Constantine, and many details of the House Chamber's appearance in the 1840s, including the red drapery. Lincoln is depicted sitting at his desk in the old Hall of the House, now called National Statuary Hall. The painting is part of a series of 21st-century portraits depicting noteworthy former members of Congress commissioned by the House of Representatives.

The painting has been featured in many articles including on Cracked.com and The Imaginative Conservative.
