Victor Schumann (21 December 1841 – 1 September 1913) was a physicist and spectroscopist who in 1893 discovered the vacuum ultraviolet. Schumann wished to study the "Extreme Ultraviolet" region. For this, he used a prism and lenses in fluorite instead of quartz allowing himself to be the first to measure spectra below 200 nm. Oxygen gas would absorb the radiation with a wavelength below 195 nm but Schumann placed the entire apparatus under vacuum. He prepared his own photographic plates with a reduced layer of gelatin.

- 빅토르 슈만(Victor Schumann, 1841년 ~ 1913년 9월 1일)은 독일의 물리학자다. 빛을 연구하여 일찍부터 자외선에 큰 관심을 가져 파장 1000의 초단파 자외선을 발견하였다. 또 자외선 사진을 찍을 때 보통의 건판을 사용함으로써 일어나는 사진의 부드럽고 연한 느낌을 없애고자 그 개량에 노력하여, 자외선 사진 촬영에 적당한 사진 건판, 즉 ''을 발견하였다. 이 문서에는 다음커뮤니케이션(현 카카오)에서 GFDL 또는 CC-SA 라이선스로 배포한 글로벌 세계대백과사전의 내용을 기초로 작성된 글이 포함되어 있습니다.
