Except for Emily Dickenson, who is an outlier and should not be counted. Seriously, she used dashes all the time. Here is a direct copy and paste of the first two stanzas of her poem "Because I count not stop for Death" from the first source I found, https://www.poetryfoundation.org/poems/47652/because-i-could-not-stop-for-death-479 https://www.poetryfoundation.org/poems/47652/because-i-could... Because I could not stop for Death – He kindly stopped for me – The Carriage held but just Ourselves – And Immortality. We slowly drove – He knew no haste And I had put away My labor and my leisure too, For His Civility – Her dashes have been rendered as en dashes in this particular case rather than em dashes, but unless you're a typography enthusiast you might not notice the difference (I certainly didn't and thought they were em dashes at first). I would bet if I hunted I would find some places where her poems have been transcribed with em dashes. (It's what I would have typed if I were transcribing them).
