Lucy Zavitske worked for External Affairs, but was assigned to King's staff from 1930 until 1949. She is mentioned in King's diary frequently, from October 1930 onwards.
King liked her and was impressed with her work. He wrote: "Miss Zavitske ... has a conscience and a real sense of duty." (Diary, January 23, 1931) Later he commented: "She is a very faithful and intelligent girl and does excellent work. It is a pleasure having her about. She is doing her very best to please." (Diary, September 18, 1931)
By 1935, he trusted her enough to dictate the diary to her. (Diary, November 12, 1935) When King travelled to the United States in November 1935, Miss Zavitske was one of the staff members who accompanied him.
She continued to work for King all through the war. In his will, King bequeathed $3,000 to Miss Zavitske.
