Hiltrud Maria Lu (née Reineke), born on September 18, 1935 in Loeningen, Germany, passed away peacefully with her loving family at her side on May 29, 2026 in Boston, MA.

Hiltrud was a devoted wife, mother, grandmother and community member. She grew up in Germany and was the daughter of Heinrich Johann Alois Reineke and Maria Reineke.

In 1963 she married Milton Ming-Deh Lu, moved to Lancaster, PA and helped to run his medical practice. She warmly welcomed patients with her compassionate nature.
