Canadian actor Kenneth Mitchell, best known for his multiple roles on the TV show “Star Trek: Discovery,” died from ALS complications on Saturday, per a statement in his official Instagram page. He was 49 years old.

“For five and a half years, Ken faced a series of awful challenges from ALS. And in truest Ken fashion, he managed to rise above each one with grace and commitment, to live a full and joyous life in each moment,” the statement reads.

The actor announced in 2020 that he was diagnosed with ALS, a progressive nervous system disease, in 2018, and he had been using a wheelchair since 2019. He told People magazine that he tried to accept the diagnosis “with grace,” and trying to see “the beauty” of it.
