Horace Warren Davis Sr., a retired longshoreman and neighborhood and civil rights activist, died April 3 of a heart attack at Bon Secours Hospital.

The Edmondson Village resident was 80.

Born in Baltimore and raised on Mount Street, Mr. Davis was a graduate of Carver Vocational-Technical High School. During the Korean War, he served as a postman with the Army in Korea.

He worked at Bethlehem Steel Corp.'s Sparrows Point plant, Fort Meade and Parks Sausage before becoming a longshoreman on the Baltimore waterfront.

Mr. Davis had served as president of International Longshoremen's Association Local 1429 in Locust Point before his retirement in 1993.

A civil rights activist, Mr. Davis participated in the historic 1963 March on Washington, where he was a monitor.

"His idol was Martin Luther King," said a daughter, Wilma Davis of Baltimore. "All of his life, he was an advocate for people's rights."

A longtime Sandtown-Winchester resident, Mr. Davis established the Committee United to Save Sandtown in the 1970s. Each year, the organization held a banquet honoring those residents who worked for the betterment of the community through political, social, religious or athletic endeavors.

In 2001, Mr. Davis was awarded an honorary degree from Eastern Theological Seminary.

He was an avid reader and enjoyed taking cruises.

His wife of 49 years, the former Myrna C. Holley, died in 1999.

Services will be held at 11 a.m. Thursday at Sharon Baptist Church, 1373 N. Stricker St.

Also surviving are a son, Horace W. Davis Jr.; another daughter, Carolyn Duane Garcia; a brother, Howard Davis; a sister, Barbara Douglas; two granddaughters; and five great-grandchildren. All are of Baltimore.
