It’s a dark day in the gaming world today as Nintendo CEO and president Satoru Iwata died today at age 55.

Nintendo announced the death of their chief executive in a statement:

Nintendo Co., Ltd. deeply regrets to announce that President Satoru Iwata passed away on July 11, 2015 due to a bile duct growth.

Iwata already missed showing up at E3 2015 this year as doctors told him not to appear. Instead, a pre-recorded video with Iwata and other executives presented as puppets became the center of the show.

As CEO and president of Nintendo, Iwata oversaw some of the greatest successes of Nintendo as a console company – with the Nintendo DS and the Nintendo Wii – he also oversaw some of the darkest days for Nintendo with the 3DS and the Wii U.

Numerous news outlets have covered his death and the gaming community is still reeling.
