Both Bartlett and Daniels are Emmy winners. In fact, they each won Emmys for St. Elsewhere, the medical drama in which they starred alongside each other. Bartlett won her first Emmy in 1986 for her role on the show, and she took the statue home again the following year.

After being nominated for his role on the show two years in a row, Daniels won the Emmy for outstanding lead actor in a drama series in 1985. He won again the following year in 1986, the same night his wife received her first big win. According to the L.A. Times, Daniels and Bartlett were the first married couple to win Emmys on the same night since 1965, when Alfred Lunt and Lynn Fontanne both won for The Magnificent Yankee.

She and Daniels overcame infidelity

In her 2023 memoir Middle of the Rainbow, Bartlett revealed that she and Daniels had both been unfaithful during the first 10 years of their marriage.

The actress admitted to having a brief affair with another actor in 1959 and shared that her husband's affair with a New York-based producer in the early '70s left her "devastated" to the point where she "could no longer tolerate any kind of open marriage."

"I guess it was a little bit of an open marriage at first, but that was very painful," she told Fox News Digital while promoting the memoir. "That didn't work well. And it was a time when people were doing that. It was at a time in New York when there was a lot of sex and a lot of people doing all kinds of things, you know – very free."

Despite their relationship struggles, their love for each other never waivered and they were eventually able to work through the rough patch.

"Bill and I have moved forward day-by-day and eventually, the days added up. We've been happy together and sad together, and somehow stayed together for seven decades," she told the outlet.

She echoed the sentiment in an interview with PEOPLE published on Jan. 24, 2023. "The marriage could have broken apart at any time those first 10 years, if one of us had, say, fallen in love with somebody, but we never did," she said. "That was never part of it. Both of us really wanted to be together. The love has never stopped."
