The fifth child and fifth son born to Halvor and Anna Munson on January 16, 1876, was named Henry William, baptized Henry Walmar. Born on the family farm in Jacksonville Township near Lawler, Iowa. He attended the rural school near his home, Luther College, Decorah, Iowa, and later graduated from Boyle's Business College in Omaha, Nebraska.

On September 20, 1905, he married Laura Barr at Omaha. She was born April 5, 1884 at Philadelphia, Pennsylvania.

At one time, he was the editor of the Beatrice (Nebraska) Gazette, and the associate editor of the Nebraska Farm Journal, a magazine, which was published at Beatrice. This magazine was owned by the Nebraska governor, McKelvie, who sold the magazine when his term as governor ended. Henry moved back to Omaha and taught accounting at Creighton University and Boyle's Business College.

Completing a correspondence course in accounting, he became a Certified Public Accountant and moved to Washington, D. C. in the spring of 1923. There he worked four years for the Internal Revenue Service, returning to Omaha as the Director of the Internal Revenue Service's Iowa-Nebraska District. His position required legal expertise as he made the final decision as to which taxpayers would be likely to produce the most additional tax dollars if the I.R.S. took them to court.

Henry died August 13, 1946, four days after suffering a stroke, at age 70. Rev. Walter Traub of Kountze Memorial Lutheran Church conducted his funeral service at Crosby-Meyer Chapel in Omaha. He was buried at Omaha in Forest Lawn Cemetery.

Laura lived another thirty years, many of them at Long Beach. She passed away at Alton, Illinois on Christmas Eve, age of 92. She, too, was buried at Omaha in Forest Lawn.
