Otto J. Mergenthaler, of Pineville, passed away unexpectedly on Tuesday, February 26, 2013. He was 73.

He was the beloved husband of 30 years to Susan O’Boyle Mergenthaler.

Born in Langhorne, he was the son of the late Emil M. and Alice Jean Conlan Mergenthaler and brother of the late Lorraine Haase.

Otto was a 1958 graduate of Neshaminy High School. After graduation, he proudly served our country in the U.S. Navy. He was the owner and operator of Van Pelt Provision Company. He was a loving father and grandfather, a lover of animals both large and small, and always a believer in fighting for the underdog.

He enjoyed fishing, walking through the forest and building furniture out of treasures that he found in the woods. Among his greatest accomplishments was building a beautiful intricate gazebo of vines and roots for his wife.

He was a man of many interests, and his main passion was collecting old bottles. He was a pillar of strength and a good friend to many. Otto will be deeply missed and always deeply loved.

In addition to his wife, Otto is survived by his children: Bryan James Mergenthaler of Pineville, Saundra Lee Mergenthaler of Hatboro, and Connie Mergenthaler of TN; his brothers: John and Tom “Pete” Mergenthaler; his sister: Irene Schulman; and three grandsons: Roman Marinucci and Adam and Brent Overholt.
