I'm slightly bothered that they didn't credit the concept of this plot to her. Maybe a description that said "inspired by a true story of Florence Nightingale" would be nice. There are just too many similarities, especially "lady with the lamp" which Florence was known for. Or maybe they credited it and I just didn't see..?

In this case I don't think there was really a need to credit Florence Nightingale. Some of the things that Florence Nightingale did may have inspired the author to write this, but I don't think this entire story is based on inspiration from the life of Florence Nightingale. The medical aspect of this story may have taken inspiration from it, and some parts of the war, but I don't really think that's enough to fully credit Florence Nightingale's life for inspiration. It's kinda like some fantasy books being based on a certain fairytale, but the author doesn't have to say, "hey this is inspired from so and so fairytale!"

No well I didn't mean that she had to credit the entire story, maybe just that part of the chapter as an author's note or somthing... Well what I really meant to say was, I don't think Florence Nightingale is copyright, I'm not an expert, and I know that a lot of mangas draw inspiration from other stories. But I guess it's just one of those things where I feel bothered but can't explain why. This credit thing is really not that big of a deal, but the thought of people who don't know Nightingale's story to think of this story as an original idea just bothered me I guess. But it really isn't a big deal just think of it as an unpopular opinion from a stranger. ╮( ̄▽ ̄)╭
The lady with the lamp is totally Florence Nightingale. It looks like the author used her as a reference plot to this story. The accomplishments of Florence Nightingale is really amazing especially for women of her time. She is considered the founder of modern nursing and brought about environmental and hygienic reforms in army hospitals. You should read about her. A wholesome badass female.
