Justice Ruth Bader Ginsburg is a pathmaker, a cultural icon known as “The Notorious R.B.G.” The Supreme Court justice was a law student when women constituted only 3 percent of lawyers in the United States and co-founder of the ACLU Women’s Rights Project and the leading advocate for gender equality.

Any one of these trailblazing achievements would be enough to explain why Ginsburg is a hero in my home—and why my two-and-a-half-year-old daughter has the T-shirts to prove it. But Ginsburg is a legal waypaver for another reason: While I do not have the data to support this hunch, I would guess that Justice Ginsburg and her late husband Marty Ginsburg were among the first two-lawyer families in the bar. Their story provides inspiration to today’s two-lawyer families. And boy do we need it.
