Rica Erickson was born Marion Frida Erickson on 16 June 1908 in Perth, Western Australia, into a family that valued the natural landscape and rural life of the colony. Her upbringing in Western Australia's countryside instilled in her a lifelong fascination with native flora, fauna, and the social history of the settlers who worked the land.
This grounding in both natural science and local history would later define her extraordinarily varied career, one that traversed botany, entomology, genealogy, and historical writing. Few women of her generation in Australia achieved recognition across such a breadth of disciplines, and her rural upbringing gave her direct, lifelong access to the ecosystems and communities she would spend decades documenting.
Her birth in the first decade of the twentieth century placed her in a generation of Australian women who had limited institutional access to scientific training, yet Erickson's self-directed curiosity and rigorous observational skills allowed her to become a self-taught expert whose contributions were eventually recognised by the highest scientific bodies in Australia. Her birthdate marks the starting point of a life that would stretch across nearly the entire twentieth century, witnessing and contributing to major developments in Australian botanical science, women's rural education, and local historical scholarship.
