Jonathan Dixon of ‘Flags Australia’ reports in the Flags of the World (FOTW); “Sekhar Chakrabarti led us to the contribution of an Irish lady to an early 20th century Indian flag by first reflecting on the women celebrated as first flag makers of national flags - in the USA, Philippines, Haiti and Cuba. In contrast, an early proposed Indian national flag was designed by Sister Nivedita. Born Margaret Noble, she was an Irish woman in India at a time when the 1905 partition of India prompted the beginning of the Swadeshi nationalist movement. She was one of the earliest to suggest that they needed a national flag, and designed a flash employing a yellow thunderbolt symbol, inspired by the Vedas, on a red field between 108 flames and Bengali text meaning "hail to the mother”. This text also appears on later nationalist flags”.
