Henry notably starred opposite Gene Autry in 1948’s "The Strawberry Room" and 1949’s "Riders in the Sky." She appeared with Lucille Ball and William Holden in 1949’s "Miss Grant Takes Richmond," Nina Foch in 1949’s "Johnny Allegro" and Marlene Dietrich in 1952’s "Rancho Notorious."

In the 1950s, Henry found herself playing a seductive siren in "The Abbot and Costello Show." She also appeared in several popular TV shows, such as "My Little Margie," "Father Knows Best" "Perry Mason" and "The Life of Riley."

For four seasons starting in 1959, Henry starred as loving mother Alice Mitchell in "Dennis the Menace," which also featured Herbert Anderson as her husband and Jay North as her mischievous son. The show was based on Hank Ketcham’s comic book character, The Hollywood Reporter noted. 

"Dennis the Menace" aired until 1963 but continued to live on for decades thanks to reruns.

"Many of the fans say, 'Oh, I always wished you were my mom' and 'My mom was jealous of you because I wanted you for a mom,’" Henry later said in a 2011 interview. "Which is pretty funny, because I don't think my own children felt that way. I have a daughter and two sons. All they knew was, I was off to work, and I wasn't with them as much as they would have liked me to be."

By the mid-‘60s, Henry took a break from acting and wouldn’t return to the screen until 1981’s "The Brady Brides," a comedy that told the story of Marcia Brady Logan (Maureen McCormick) and Jan Brady Covington (Eve Plumb) and their lives as newlyweds with their husbands. Henry steadily worked over the years and made her mark on hit TV shows like "Newhart," "Dallas" and "Doogie Howser, M.D.," among others.

Henry’s last credited role was that of Mary-Elizabeth Clinch in 2012’s "Parks and Recreation."

Henry was married to architect Craig Ellwood from 1949 until 1977. He died in 1992, People magazine reported. She leaves behind their three children.
