Yeah fuck you Mikhail Aleksandrovich Bonch-Bruevich

it took me like half an hour to find a leftist born in 1888. Cool guy, glad I found him. He did radio improvements for Lenin, here is a letter Lenin wrote to him

"I take this opportunity to express my deep gratitude and sympathy for the great work and inventions in the field of radio you do. Newspaper without paper and without distance that you create will be a great thing. Fully and I promise you all possible assistance to this and similar works. With best wishes." Ulyanov

edit: I also found a Moldovan socialist revolutionary party member who voted for unifying Bessarabia with communist Moldova but that's it and his death date is literally just "20th century" Ignație Budișteanu spoopy

edit 2: holy shit fucking Bukharin was born in 1888, well that beats the other two I guess
