Sima's two daughters, Ana Lozanić (1882-1973) (later married to minister Dr. Vojislav Marinković) became a well-known painter and Jelena Lozanić who, like her father, affirmed in humanitarian work and in the battle for women's rights, participated in international congresses in the United States in 1915 as a Serbian Red Cross delegate to enlist aid for her war desolated country.

Since the war continued in Serbia, she stayed in America until the year 1920, when she married John Frothingham, the great benefactor to Serbian people.

Together with Michael Pupin, Mr. and Mrs. John Frothingham contributed greatly in delivering humanitarian aid.

[citation needed] An exhibition "Sima Lozanić in Serbian science and culture" was held in his honor, organized by Serbian Academy of Sciences and Arts from January to March 1993, in Academy's gallery in Knez Mihailova street in Belgrade.

His life and work was especially investigated by chemist Snežana Bojović, who wrote a 262-page book Sima Lozanić.
