ISABELLE BOOK

It is with sadness and gratitude for a life well lived, that we announce the passing of our family matriarch Isabelle Book. Izzy was born on November 21, 1925, and passed away peacefully on Thursday, February 6, 2025.
She was predeceased by her parents Clara and Jacob Brownstein, her brother Walter, her sister Minnie Goldman, her beloved husband Arthur, her brother-in-law Noel and a fabulous group of women who shared a friendship that lasted decades.
She is survived by her 4 children, Warren and Faye Book, Marilyn and David Pressman, Jacqueline and Jory Stillwater and David and Elaine Book. She was a very proud Baba to Hilary Book, Deborah Book and Mike James, Laurie and Ginny Stillwater, Kayleigh and Barrett Ruggles, Adam Book and Gabe Bloomfield-Book and Seth Book and Amy Shore. She so enjoyed seeing pictures and videos of her great-grandchildren Hugo, Marcus, Reese, Maverick, Richie and Sullivan. She will also be greatly missed by her sister -in- law and dear friend Shirley Book.
Izzy had a great sense of humour and was often unable to get to the punchline of a joke because she was laughing so hard. She could be stubborn and strong minded. She would dig in her heels if she felt she was being pushed to make a decision she wasn’t ready to make. Izzy enjoyed time with family and friends but was also very comfortable with her own company.
Izzy knew what it meant to be a friend. She was a kind compassionate woman who cherished the people in her life and was always our biggest fan. Our mom was a quality human being who never forgot a birthday or anniversary. Izzy lived by the Golden Rule. She lived a long, healthy life but remained seriously young at heart.
There are memories to last a lifetime, ones that we will keep close as we honour her memory. We were blessed to have her for as long as we did, strong, loving and sharp until almost the end. She modeled what it meant to live a good life. She also did it on her terms.
The funeral took place on Sunday, February 9 at the B’nai Abraham Cemetery with Rabbi Kliel Rose officiating. Pallbearers were her grandchildren.
The family wishes to thank the incredible staff at the Rosewood (Maple House) where she lived. She bonded with many of the wonderful people who cared and supported her there.

Naomi Lander Rosenthal February 14, 1940 – February 12, 2025

Naomi Lander Rosenthal was born in Winnipeg and passed away two days shy of her 85th birthday. She was the daughter of Drs. Jacob Joseph (Jack) Lander, a respected and beloved family practitioner in Winnipeg, and Clara (Shnay) Lander, a literary scholar and past President of the Winnipeg Art Gallery’s Board of Governors.
Naomi was a classically trained pianist and performed both formally and informally in many venues. She was always asked to play at any party where there was a piano. Her favorite classical piece was Bach’s Jesu Joy of Man’s Desiring, which readers can listen to and enjoy here. Naomi was heavily influenced by the version played by the pianist Glenn Gould, which approximates how Naomi approached it. Naomi had a great appreciation for complexity in musical style and composition. Her piano repertoire extended from Bach and Brahms to Elton John and Billy Joel.
Naomi lived in Toronto from 1968-1988 and then moved back to Winnipeg in 1989 to help care for her father when he became ill. She worked in senior executive assistant roles from the 1970s through the early 1990s in insurance, government and the non-profit sectors before retiring at age 65. Her work ethic, perfectionism and sense of mission throughout her career made Naomi a beloved team member, who also fostered life-long friendships with her supervisors and even their families.
In addition to music, Naomi had many interests, including gourmet cooking, film, science fiction and fantasy, and politics. Naomi could engage anyone in any number of subjects and was particularly interested in health and medicine. Naomi will now go on to teach medical students through the University of Manitoba’s Rady Faculty of Health Sciences’ body donation program.
Naomi is survived by her daughters and sons-in-law, Ahava Rosenthal and Michael Shore, of Boston, MA; M. Sara Rosenthal and Kenneth Ain of Lexington, Kentucky; her grandchildren, Kayla Shore and Jacob Shore; her step-grandchildren, Maxwell Ain and Jacob Ain; her sisters, Myra Lander of San Mateo, California, and Judith Lander of Toronto; nephews Kalan Vuksanovich and Stephen Israels and many extended family members from the Lander families, Shnay families, and Rothberg families.
The family wishes to thank Richard (Dick) and Joanne Rothberg; Naomi’s wonderful caregivers at The Key, homecare assistance in Winnipeg, including Brian Boxall and Althea King; the Simkin Centre; and Elena Episcope for helping to make Naomi’s final years so much more comfortable.
A remembrance of Naomi will be held on Thursday evening, February 20th at 7 pm at 202 Lamont Blvd in Winnipeg. Donations in Naomi’s memory may be made to CancerCareManitoba or to the organization of your choice.
