she was photographing the extensive Electra Power Project—an early hydroelectric power project in California. This project, located near her home on the Mokelumne River, was completed in 1902 after four years of construction. According to family tradition, Standard Electric of California, later named Pacific Gas & Electric Company, hired her to photograph the project. No records have been found to substantiate this claim. Many of these photographs are housed in the Brigham Young University Library collection bearing her name. She became a member of the Eastern Star, the women's group of the Masonic Lodge, in 1912. San Francisco earthquake In 1906, at age 22, Irvine had made plans to take a year-long trip around the world. Irvine left from Stockton and arrived in San Francisco on April 18, 1906, just hours after the earthquake. Armed with a large supply of photographic materials, Irvine found an abandoned baby stroller and loaded her equipment in it, so as not to arouse suspicion from the armed guards stationed around the city. These guards were stationed around the city at the request of city government officials who were trying to conceal the magnitude of the damage, and the stroller allowed Irvine to move freely throughout the city and take photographs of what she came across. She remained in San Francisco for three days taking photos before returning to Mokelumne Hill, evidently forgoing her travels. On the 1910 census, Irvine reported herself to be a professional photographer, but by 1920 she was working as a school teacher. She taught school until about 1931, when her declining health no longer permitted her to work. One of her former students characterized her as fair, but strict, and a good teacher. Health and later years During her later years, Irvine suffered from a medical condition which caused her severe joint pains throughout her body. Given that her condition had never been properly diagnosed, Irvine's doctors decided to treat it with painkillers. Irvine became addicted to the painkillers and was later sent to a six-week drug rehabilitation program in San Francisco following a suicide attempt. Following her treatment, Irvine had a relapse and became an alcoholic as well, leading to another hospitalization. She also began losing her hearing at an early age and was nearly deaf by age 45. Irvine and her brother Robert lived together most of their lives, as she never married and he did not marry
