Zewditu I of Ethiopia died on 1930-04-02.

Zewditu I of Ethiopia was born on 1876-04-29.

He had four children. two children From Weizero Weleteselasie Jilow from Sodo, one ( Zewditu) from weizero Banch,i and one (Shewaregga) from from Weizero Dessale

My guess is Empress Zewditu of Ethiopia who appeared on a 1918 stamp of Ethiopia.

You didn't ask from what country, so it's hard to say. If you are talking about the United States, the first Black woman to appear on a postage stamp was Harriet Tubman on Feb 1, 1978.
