Susan G. Komen Breast Cancer Foundation

Explanation:

The "Susan G. Komen Breast Cancer Foundation" was established by Nancy Brinker in 1982 in memory of her late sister (Susan Goodman Komen) who died of breast cancer at the age of 36. The organization was meant to help in the research and spread of breast cancer awareness to people.

It became known for its "pink ribbon" logo that you often see during Breast Cancer Awareness month (October). The organization holds the biggest fundraising event dedicated to breast cancer awareness. Such event started in 1983 with 800 participants. Later on, the participants reached more than a million.
