As Gay Sigel walked through the doors at One IBM Plaza in Chicago, fresh out of law school and ready to launch her career as an attorney at Jenner & Block, she could not have envisioned the tremendous impact she would have on her clients, her colleagues, and her community over the next 39 years. Gay started her legal career as a general litigator, but Gay and Bob Graham were quick to realize how the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) was creating a new and exciting area of the law that was increasingly important for the firm's clients: Environmental Law. Gay and Bob saw an opportunity to specialize in that area and founded Jenner & Block's Environmental Health and Safety Practice. Gay has been an ever-present force in the EHS community ever since.

Over her 39-year career at Jenner & Block, Gay has worked on some of the most significant environmental cases in the country for clients ranging from global Fortune 50 corporations to environmental organizations to individuals. For more than a decade, she taught environmental law at Northwestern University, helping shape the next generation of environmental lawyers. She has worked on issues of global impact, like those affecting climate change, issues of local impact like those related to combined sewer overflows to the Chicago River, and issues of individual impact like those involving employee safety and health. No matter the subject, Gay has always been a tireless advocate for her clients. We often describe her as the Energizer Bunny of environmental lawyers: she is the hardest working attorney we have ever met. 

Gay's true passion is to make this world a better, more just place for others. So, throughout her career as an environmental, health, and safety lawyer, Gay has devoted her time, energy, and emotional resources to innumerable pro bono cases and charitable and advocacy organizations. Her pro bono work includes successfully protecting asylum applicants, defending criminal cases, asserting parental rights, and defending arts organizations in OSHA matters. Among her many civic endeavors, Gay was a founding member of the AIDS Legal Council of Chicago (n/k/a as the Legal Council for Health Justice); she was the Secretary and active member of the Board of Directors for the Chicago Foundation for Women; and she was on the Board of the New Israel Fund. Gay continues to promote justice wherever she sees injustice, including as an advocate for women's rights, particularly for women's reproductive rights.

In both her environmental, health, and safety practice as well as her pro bono and charitable work, Gay is a tremendous mentor to younger (and even older) attorneys. She is curious, committed, exacting, fearless, and demanding (though more of herself than of others). We all give Gay much credit for making us the lawyers we are today.

Gay is leaving Jenner & Block to embark on her next adventure. She is returning to public service as Corporate Environmental Counsel for the City of Chicago. The City and its residents will be well served as Gay will bring her vast experience and unparalleled energy to work tirelessly to protect the City and its environment. We will miss working with and learning from Gay on a daily basis, but we look forward to seeing the great things she will accomplish for the City of Chicago. We know we speak for the entire firm as we wish Gay bon voyage—we will miss you!
