Horace Nathan Sampson, a native Philadelphian who built a successful home and lumber company before retiring to La Jolla, Calif., died Sept. 30. He was 98.

He scored a major success ­also as a volunteer, helping out with the Service Corps of Retired Executives for 25 years.

Horace and Dotty — his wife of nearly 70 years who preceded him in death almost a year ago — were a formidable team of civic leaders who had many friends related to their various volunteer passions.

He was a 32nd Degree Mason and received many awards for his community service and charitable activities.

Sampson is survived by a daughter, Allison; sons Steven, Gary and Glen; five grandchildren; a great-grandchild; and several nieces and nephews.
