Kate Spade's husband Andrew shared a touching tribute to his late wife in which he praised her "magical spirit." 

Andrew Spade, the husband of famed designer Kate Spade who lost her life to suicide last year, has paid tribute to his talented wife on the first anniversary of her death. 

Talking about Spade's "boundless generosity, unflappable honesty and kindness to all living things," the widower posted to Instagram to share an image of a tree he and their daughter Frances would plant in her memory. 

The designer married Andrew Spade in 1994, a year after the couple started the fashion brand Kate Spade New York together.

Never officially named Kate Spade, the 55-year-old was born Katherine Noel Frances Brosnahan in Kansas City, Missouri, on December 24, 1962, to Earl Francis Brosnahan, Jr. and June Mullen. Three of her great-grandparents were Irish emigrants. The company was named as a combination of her own and Andy Spade’s name.

Her husband is believed to have been in their Park Ave apartment at the time of her death while their 13-year-old daughter Frances Beatrice was at school. It was reported soon afterward that the couple had split before her tragic death. 

The full anniversary post read: "Dear Katy, this tree is for you. Bea and are planting it outside of our big window to keep your magical spirit and energy close to us everyday. It will bless our new home in California and radiate your essence 365 days a year.

"You were illumines and we feel your presence wherever we go. I want to thank you for all of the wonderful gifts you gave me over the years. For your beauty, intelligence and grace under pressure. For your boundless generosity, unflappable honesty and kindness to all living things. For your strength, courage and conviction to your ideals. For your belief in me and so many others. For your infectious laughter and sharp wit.

Dear Katy, this tree is for you. Bea and are planting it outside of our big window to keep your magical spirit and energy close to us everyday. It will bless our new home in California and radiate your essence 365 days a year. You were illumines and we feel your presence wherever we go. I want to thank you for all of the wonderful gifts you gave me over the years. For your beauty, intelligence and grace under pressure. For your boundless generosity, unflappable honesty and kindness to all living things. For your strength, courage and conviction to your ideals. For your belief in me and so many others. For your infectious laughter and sharp wit. There was never a dull moment with you. Through the peaks and valleys and alleyways we serpentined through together you were always there. We grew up together, helped raise one another yet vowed to retain our innocence as best we could. You taught me that modesty is always the best policy, to see the good in everyone and to stand up for the crazy and less fortunate. You hated hype and loved the humble. You called me out on my bullshit yet were nonjudgmental. You talked straight and let me know when I was was being cynical or sarcastic. You were my best friend, my confidant, my partner in life, business and mischief. The ying to my yang and the zig to my zag. We played ping pong with ideas. Our shared passion for The Golden Rule, Kipling’s “If”, Strunk and White, Atticus Finch and millions other things bound us together like superglue. You were and still are my Superwoman. I hope you know how many people you inspired through the example you set in the way you lived and the work you created. You were and still are my favorite poem. I can’t tell you how grateful I am for all you have given me and so many others. May your bright, multicolored spirit shine down on us everyday. Heaven is lucky to have you but please know you are truly missed by us still here on earth. Love, Andy
