Hanns J. Derke, 60, of Avondale, PA and formerly of Wilmington, DE, lost his courageous battle with cancer on April 3, 2018.

Hanns is survived by his wife, Tina, of 36 years; his son, Nick; brother, Wolfgang Derke; nephews Robert and Richard Derke; "chosen" brother, Gary Munch and his beloved family, Lara, Luke, Sam and Greta Munch; as well as numerous aunts, cousins, and an uncle.

Hanns was born on August 14, l957 to Vera and Waldemar Derke (both deceased) in Bergisch Gladbach, Germany. The family moved to Delhi, NY in 1961. Hanns attended school in Delhi, NY, as well as in Sunnyside, WA; Modesto, CA and college in Brownsville, TX.

In, 1976, Hanns joined the family business. In 1981, Hanns and Tina married and moved to Spartanburg, SC where Hanns worked for a major German company, RENK, at their U.S. headquarters in Spartanburg, SC.

After a few years, Hanns and Tina moved back to DE and Hanns returned to Advanced Machinery, where he was Vice President of Sales and worked with his brother, Wolfgang since his return.

Hanns, over the years, served on the Board of Wilmington Montessori, coached little league baseball and umpired baseball for the IBUA. He was happiest playing with his poker buddies of Brittany Hills and relaxing on the deck at his little piece of heaven at their house on the bay in Rehoboth Beach.

Above all else, he was a loving and devoted husband and father. He touched many lives and will be deeply missed by those who knew him.

A gathering for family and friends for a "celebration of life" will take place on Sunday, April 22 from 2-6 p.m. at Merchant Social, 1500 Chesapeake Club Drive, North East, MD 21901 (www.merchantsocial.net). Hanns was passionate about demanding human rights for everyone and conserving our land and waters to preserve their beauty so the family suggests honoring Hann’s memory by sending a contribution to Amnesty International USA, 5 Penn Plaza, 16th Floor, New York, NY 10001 or The Nature Conservancy, Attn: Treasury, 4345 N. Fairfax Drive, Suite 100, Arlington, VA 22203. Messages of condolence may be sent to www.mccreryandharra.com
